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?
The total number of residents polled is 500 + 500 = 1000.
The total number of residents who would vote for Candidate A is 346 + 248 = 594.
The percentage of the total polled residents who would vote for Candidate A is (594/1000) * 100% = 59.4%.
Therefore, approximately 59.4% of the total polled residents would vote for Candidate A as the town mayor.
Thanks! I have a nother one for you:
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?
To find the mean height of the first set of trees, we take the sum of their heights and divide by the total number of trees:
(85.4 + 87.6 + 87.1 + 85.6 + 85.9 + 85.3 + 84.9 + 83.7 + 84.0 + 85.2)/10 = 85.48 feet
To find the mean height of the second set of trees, we take the sum of their heights and divide by the total number of trees:
(87.1 + 88.0 + 84.2 + 85.3 + 86.5 + 84.2 + 83.2 + 84.1 + 85.2 + 87.3)/10 = 85.32 feet
The difference between the mean heights of the two sets of trees is:
85.48 - 85.32 = 0.16 feet
Therefore, the difference between the mean heights of the two sets of trees is approximately 0.16 feet.
Here are the math quiz scores for Student 1 and Student 2.
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 *Blank*
. The range of Student 2’s math quiz scores is *Blank*
. Based on the range, Student *Blank*
performed more consistently on the math quizzes.
To find the range of a set of data, we subtract the smallest value from the largest value.
For Student 1:
92 - 75 = 17
So the range of Student 1’s math quiz scores is 17.
For Student 2:
93 - 72 = 21
So the range of Student 2’s math quiz scores is 21.
A smaller range generally indicates greater consistency because it means that the scores are clustered more closely together, while a larger range means that there is a greater difference between the highest and lowest scores.
Therefore, based on the ranges, Student 1 performed more consistently on the math quizzes, as their scores had a smaller range.
