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.
