Clover wants to know the average daily temperature in their town during the summer. They chose 2 random samples of 10 consecutive days and recorded the daily high temperatures The daily high temperatures are listed in Fahrenheit.
Sample 1: 78, 82, 85, 87, 90, 85, 79, 86, 91, 88
Sample 2: 81, 79, 80, 86, 89, 92, 82, 88, 84, 87
Find the mean daily temperatures of each sample and calculate the difference between these mean daily high temperatures.
Sure! I'd be happy to help you learn Japanese. Japanese is a beautiful and complex language, and learning it can be challenging but rewarding. Here are some basic Japanese language concepts and phrases to get you started:
1. The basic Japanese writing system consists of three scripts: hiragana, katakana, and kanji. Hiragana and katakana are phonetic scripts consisting of 46 characters each. Kanji are Chinese characters used in Japanese writing.
2. Japanese grammar is very different from English grammar. Japanese sentences are structured subject-object-verb, and the verb always comes at the end of the sentence. There are no articles (a, an, the) in Japanese, and verb tenses are not used in the same way as in English.
3. Japanese pronunciation is relatively straightforward. Each character has one associated sound, and there are no silent letters. However, there are some sounds in Japanese that do not exist in English, such as the "tsu" sound.
4. Basic Japanese phrases:
- Hello: こんにちは (Konnichiwa)
- Goodbye: さようなら (Sayonara)
- Thank you: ありがとう (Arigatou)
- Excuse me: すみません (Sumimasen)
- Yes: はい (Hai)
- No: いいえ (Iie)
I hope this introduction to Japanese has been helpful! Let me know if you have any further questions.
To find the percentage of people who own birds among 200 people, you can use the following formula:
Percentage = (Number of people who own birds / Total number of people) x 100%
Plugging in the values given in the question, we get:
Percentage = (20 / 200) x 100% = 10%
Therefore, 10% of the 200 people own birds.
To find the mean daily temperature of Sample 1:
1. Add up all the temperatures:
78 + 82 + 85 + 87 + 90 + 85 + 79 + 86 + 91 + 88 = 851
2. Divide by the number of temperatures (which is 10):
851/10 = 85.1
So the mean daily temperature of Sample 1 is 85.1 degrees Fahrenheit.
To find the mean daily temperature of Sample 2:
1. Add up all the temperatures:
81 + 79 + 80 + 86 + 89 + 92 + 82 + 88 + 84 + 87 = 848
2. Divide by the number of temperatures (which is also 10):
848/10 = 84.8
So the mean daily temperature of Sample 2 is 84.8 degrees Fahrenheit.
To find the difference between these mean daily temperatures:
85.1 - 84.8 = 0.3
So the difference between the mean daily temperatures of Sample 1 and Sample 2 is 0.3 degrees Fahrenheit.

Out of 200 people only 20 people own birds, what percentage is that?
Team 1: 6, 0, 4, 17, 3, 12
Team 2: 23, 14, 22, 14, 17, 22
These are the scores for 2 randomly selected teams. Find the range of the number of goals scored by each team. Based on the range which team has a more consistent number of goals
To find the range of the number of goals scored by each team, you need to subtract the lowest score from the highest score for each team.
For Team 1:
Highest score = 17
Lowest score = 0
Range = 17 - 0 = 17
For Team 2:
Highest score = 23
Lowest score = 14
Range = 23 - 14 = 9
Therefore, the range of the number of goals scored by Team 1 is 17, and the range for Team 2 is 9.
A smaller range indicates that the team has a more consistent number of goals, as their scores are all close to each other. Based on the ranges calculated, Team 2 has a smaller range, and thus a more consistent number of goals compared to Team 1.
fifteen student are randomly selected from 2 different classes. They were asked how many books they read over the summer. Their responses are as follows. Find the median number of books read by each class. Which class has a higher median of books read?
Class A: 0, 5, 3, 6, 7, 10, 1, 1, 4, 5, 6, 4, 5, 4
Class B: 2, 2, 4, 3, 0, 0, 6, 7, 10, 9, 6, 5, 3, 1, 2
To find the median number of books read by each class, we need to first put the data in order from smallest to largest:
Class A: 0, 1, 1, 3, 4, 4, 4, 5, 5, 5, 6, 6, 7, 10
Class B: 0, 0, 1, 2, 2, 2, 3, 3, 4, 5, 6, 6, 7, 9, 10
To find the median, we need to identify the middle number in the data set. If there are an even number of data points, we take the average of the two middle numbers.
For Class A, there are 14 data points, so the median is the average of the 7th and 8th numbers:
Median for Class A = (4+5)/2 = 4.5
For Class B, there are 15 data points, so the median is the 8th number:
Median for Class B = 3
Therefore, Class A has a higher median of books read, with a median of 4.5 compared to Class B's median of 3.

D) Statements 1 and 2 are true
Alex plays in a softball league. He wants to know how many other players in the league also play basketball. Because there are 225, he chooses the names of 45 of the players and asked them whether or not they play basketball. Describe the population and the sample. What is the size of the population, and what's the size of the sample? Show your work.
The population in this scenario would be all players in the softball league, while the sample would be the 45 players that Alex chose to survey about whether or not they play basketball.
The size of the population is given as 225 players. The size of the sample is 45 players, which means that Alex chose to survey 45 out of the 225 players in the population.
It's important to note that the sample should be representative of the population to accurately estimate the proportion of players who also play basketball. However, we don't have enough information to determine whether or not this is the case.
what percentage is 45 people out of 225?
To find the percentage of 45 people out of 225, we can use the formula:
Percentage = (part/whole) x 100%
where "part" is the number of people we are interested in (in this case, 45 people) and "whole" is the total population (225 people).
Plugging in the numbers, we get:
Percentage = (45/225) x 100% = 20%
Therefore, 45 people represents 20% of the total population of 225 people.
To find the median number of books read by each class, let's first put the data in order:
Class A: 0, 1, 1, 3, 4, 4, 4, 5, 5, 6, 6, 7, 8, 10
Class B: 0, 0, 1, 2, 2, 2, 3, 3, 4, 5, 6, 6, 7, 9, 10
For Class A, we have 15 data points, which means the median will be the average of the middle two numbers:
Median for Class A = (5 + 6)/2 = 5.5
For Class B, we have 15 data points, which means the median will be the middle number:
Median for Class B = 4
Therefore, Class A has a higher median number of books read, with a median of 5.5 compared to Class B's median of 4.
To determine which of the statements are true, we need to calculate the mean, median, and range of each company's ages:
For Company A:
Mean = (34+28+36+27+45+44+30+42+40+50+48+52+45+39+38)/15 = 40
Median = 40
Range = 52-27 = 25
For Company B:
Mean = (29+32+48+51+49+37+33+35+36+40+45+48+43+43+44+48)/16 ≈ 41.69
Median = 43.5
Range = 51-29 = 22
Based on these calculations, we can determine which of the statements are true:
1. The mean age of employees from Company A is lower than the mean age of employees from Company B. (False)
2. The median age of employees from Company A is the same as the median age from Company B. (True)
3. The range of ages of employees from Company A is higher than the range of Company B. (True)
Therefore, the answer is A) Statements 1 and 3 are true.
