The points by football team are 17, 23, 15, 21, 7 and 13. What is the range?
____ points
The range is the difference between the highest and lowest values in a dataset.
In this case, the highest value is 23 and the lowest value is 7.
Therefore, the range is 23 - 7 = 16 points.
To find the range, we need to determine the difference between the highest and lowest values in the dataset.
The highest value in the dataset is 36 (from 2017) and the lowest value is 22 (from 2015).
Therefore, the range of the number of members is:
36 (highest value) - 22 (lowest value) = 14 members.
Therefore, the range is 14 members.
To find the percentage of residents who would vote for Candidate A as the town mayor, we need to calculate the total number of residents who would vote for Candidate A from both samples and compare it to the total number of residents polled.
From Sample 1, 346 residents would vote for Candidate A.
From Sample 2, 248 residents would vote for Candidate A.
Therefore, the total number of residents who would vote for Candidate A is 346 + 248 = 594.
The total number of residents polled is 500 + 500 = 1000.
To find the percentage, we do (594/1000) * 100% = 59.4%.
Therefore, approximately 59.4% of the total polled residents would vote for Candidate A as the town mayor.
To find the range of each student's math quiz scores, we need to subtract the lowest score from the highest score.
For Student 1:
Highest score = 92
Lowest score = 75
Range = 92 - 75 = 17
For Student 2:
Highest score = 93
Lowest score = 72
Range = 93 - 72 = 21
Based on the range of the scores, Student 1 has a range of 17 and Student 2 has a range of 21.
Therefore, Student 1 performed more consistently on their math quizzes as they have a smaller range in scores.

A poll is conducted to determine who is most likely to win the election for town mayor. Two random samples of 500 residents each are polled. The data is as follows.
Candidate A Candidate B Total
Sample 1: 346 154 500
Sample 2: 248 252 500
What percentage of the total polled residents would vote for Candidate A as the town mayor?
____%
To determine the average height of trees in a national forest, 10 trees are randomly selected. Their heights in feet are 85.4, 87.6, 87.1, 85.6, 85.9, 85.3, 84.9, 83.7, 84.0, and 85.2. To ensure the accuracy of the data, another set of 10 trees is randomly selected. Their heights are 87.1, 88.0, 84.2, 85.3, 86.5, 84.2, 83.2, 84.1, 85.2, and 87.3. What is the difference between the mean heights of the trees of these two random samples?
the correct answer is 0.04
Here are the math scores for student 2 and student 1.
Student 1: 75 80 84 79 92 86 88 86 86 90
Student 2: 83 85 91 93 72 85 76 80 82 89
Find the range of each student's math quiz scores. Based on the range which student performed more consistently on their math quizzes?
The range of Student 1's math quiz scores is ____ . The range of Students 2's math quiz scores is ____ .Base on the range Student ____ performed more consistently on the math quizzes.
To find the difference between the mean heights of the two random samples of trees, we first need to calculate the mean height for each sample and then find the difference between the means.
For the first sample:
Total height = 85.4 + 87.6 + 87.1 + 85.6 + 85.9 + 85.3 + 84.9 + 83.7 + 84.0 + 85.2 = 865.7
Mean height = 865.7 / 10 = 86.57
For the second sample:
Total height = 87.1 + 88.0 + 84.2 + 85.3 + 86.5 + 84.2 + 83.2 + 84.1 + 85.2 + 87.3 = 869.1
Mean height = 869.1 / 10 = 86.91
The difference between the mean heights of the two samples is:
86.91 - 86.57 = 0.34
Therefore, the difference between the mean heights of the two random samples of trees is 0.34 feet, not 0.04 as stated in the question.
