There are 18,472 registered voters. Based on the data from the random survey, which BEST predicts the number of actual votes that will be cast for Candidate A?
Responses
A 11,540 votes
B 7,916 votes
C 9,790 votes
D 12,147 votes
To find the best prediction for the number of actual votes that will be cast for Candidate A, we need to multiply the percentage of voters who said they will vote for Candidate A (53%) by the total number of registered voters (18,472).
53% of 18,472 is (0.53 x 18,472) = 9,790 votes.
Therefore, the best prediction for the number of actual votes that will be cast for Candidate A is C) 9,790 votes.

Percentages
Which statement is best supported by the information in the box plots?
Responses
A The median of the data for class 1 is greater than the median of the data for class 2.The median of the data for class 1 is greater than the median of the data for class 2. - no response given
B The interquartile range of the data for class 2 is greater than the interquartile range of the data for class 1.The interquartile range of the data for class 2 is greater than the interquartile range of the data for class 1. - no response given
C The minimum test score for class 1 is less than the minimum test score for class 2.The minimum test score for class 1 is less than the minimum test score for class 2. - no response given
D The range of the data for class 1 is less than the range of the data for class 2.
The best statement supported by the information in the box plots is:
D) The range of the data for class 1 is less than the range of the data for class 2.
We can see from the box plots that the maximum score for class 1 is approximately 88, while the maximum score for class 2 is approximately 99. Therefore, the range of the data for class 2 is greater than the range of the data for class 1.

Students at Remington High School were polled regarding their favorite drinks. The results are shown on the circle graph.
If 630 students were polled, how many preferred cola?
Responses
A 130130 - no response given
B 122122 - no response given
C 126126 - no response given
D 118
Looking at the circle graph, we can estimate that the fraction of students who preferred cola is a little more than 1/5 (between 1/5 and 1/4).
To find the actual number of students who preferred cola, we can multiply the total number of students polled (630) by the fraction of students who preferred cola:
1/5 x 630 = 126
Therefore, the number of students who preferred cola is C) 126.

Which statement is best supported by the data?
Responses
A The mean of the data after exercise is greater than the mean of the data before exercise.The mean of the data after exercise is greater than the mean of the data before exercise. - no response given
B The median of the data after exercise is less than the median of the data before exercise.The median of the data after exercise is less than the median of the data before exercise. - no response given
C The mode of the data before exercise is greater than the mode of the data after exercise.The mode of the data before exercise is greater than the mode of the data after exercise. - no response given
D The range of the data before exercise is less than the range of the data after exercise.
The best statement supported by the data is:
D) The range of the data before exercise is less than the range of the data after exercise.
Looking at the dot plots, we can see that the range of the data before exercise is about 23 beats per minute (from approximately 55 to 78), while the range of the data after exercise is about 29 beats per minute (from approximately 75 to 104). Therefore, the range of the data after exercise is greater than the range of the data before exercise.
