The range is 16 points.
To calculate the range, we subtract the lowest score from the highest score.
Highest score: 23
Lowest score: 7
23 - 7 = 16
Therefore, the range is 16 points.

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?
(1 point)
To find the percentage of residents who would vote for Candidate A as the town mayor, we need to add the number of residents who support Candidate A in both samples and then divide by the total number of residents polled.
In Sample 1:
Number of residents supporting Candidate A = 346
In Sample 2:
Number of residents supporting Candidate A = 248
Total number of residents supporting Candidate A = 346 + 248 = 594
Total number of residents polled = 500 + 500 = 1000
To find the percentage, we calculate:
(594 / 1000) * 100 = 59.4%
Therefore, 59.4% of the total polled residents would vote for Candidate A as the town mayor.
In Sample 1:
Number of residents supporting Candidate A = 346
In Sample 2:
Number of residents supporting Candidate A = 248
Total number of residents supporting Candidate A = 346 + 248 = 594
Total number of residents polled = 500 + 500 = 1000
To find the percentage, we calculate:
(594 / 1000) * 100 = 59.4%
Therefore, 59.4% of the total polled residents would vote for Candidate A as the town mayor.
The numbers of miles Ron biked are 31, 35, 49, 32, 45, 29, 33, 28, and 40.
Determine the range of this data set.(1 point)
Determine the range of this data set.(1 point)
The range of a data set is the difference between the largest and the smallest values.
To find the range of the data set of miles Ron biked (31, 35, 49, 32, 45, 29, 33, 28, 40), we first need to identify the smallest and largest values in the set:
Smallest value: 28
Largest value: 49
Next, we calculate the range by subtracting the smallest value from the largest value:
49 - 28 = 21
Therefore, the range of the data set is 21 miles.

To determine which data set has the smallest range, we need to calculate the range for each data set and compare them.
1. Range of {50, 30, 10, 0, 80, 100}:
Smallest value: 0
Largest value: 100
Range: 100 - 0 = 100
2. Range of {324, 318, 367, 312, 389, 337}:
Smallest value: 312
Largest value: 389
Range: 389 - 312 = 77
3. Range of {37, 19, 40, 54, 75, 68}:
Smallest value: 19
Largest value: 75
Range: 75 - 19 = 56
4. Range of {148, 145, 117, 148, 199, 172}:
Smallest value: 117
Largest value: 199
Range: 199 - 117 = 82
Therefore, the data set {324, 318, 367, 312, 389, 337} has the smallest range, which is 77.
1. Range of {50, 30, 10, 0, 80, 100}:
Smallest value: 0
Largest value: 100
Range: 100 - 0 = 100
2. Range of {324, 318, 367, 312, 389, 337}:
Smallest value: 312
Largest value: 389
Range: 389 - 312 = 77
3. Range of {37, 19, 40, 54, 75, 68}:
Smallest value: 19
Largest value: 75
Range: 75 - 19 = 56
4. Range of {148, 145, 117, 148, 199, 172}:
Smallest value: 117
Largest value: 199
Range: 199 - 117 = 82

Sample 2 43 64 61 32 200
Based on the two samples, what percentage of the people prefer cashew nuts?
Almond Pistachio Cashew Walnuts Total
Sample 1 40 62 63 35 200
Sample 2 43 64 61 32 200
Based on the two samples, what percentage of the people prefer cashew nuts?
To find the percentage of people who prefer cashew nuts based on the two samples, we first need to calculate the total number of people who prefer cashew nuts from both samples.
In Sample 1:
Number of people who prefer cashew nuts = 63
In Sample 2:
Number of people who prefer cashew nuts = 61
Total number of people who prefer cashew nuts = 63 + 61 = 124
Total number of people polled = 200 + 200 = 400
To find the percentage, we calculate:
(124 / 400) * 100 = 31%
Therefore, 31% of the people prefer cashew nuts based on the two samples.
In Sample 1:
Number of people who prefer cashew nuts = 63
In Sample 2:
Number of people who prefer cashew nuts = 61
Total number of people who prefer cashew nuts = 63 + 61 = 124
Total number of people polled = 200 + 200 = 400
To find the percentage, we calculate:
(124 / 400) * 100 = 31%
Therefore, 31% of the people prefer cashew nuts based on the two samples.
The following data sets represent the highway fuel efficiency in miles per gallon (mpg) of randomly selected cars from two car companies. Which company has cars that are more consistent in highway fuel efficiency?
Car Company A: 35, 28, 35, 30, 31, 36, 35, 30
Car Company B: 29, 33, 40, 27, 34, 34, 34, 25
Car Company A: 35, 28, 35, 30, 31, 36, 35, 30
Car Company B: 29, 33, 40, 27, 34, 34, 34, 25
To determine which car company has cars that are more consistent in highway fuel efficiency, we will calculate the range for each set of data. The smaller the range, the more consistent the data is.
For Car Company A:
Range = Highest value - Lowest value
Highest value: 36
Lowest value: 28
Range = 36 - 28 = 8
For Car Company B:
Range = Highest value - Lowest value
Highest value: 40
Lowest value: 25
Range = 40 - 25 = 15
Comparing the range values:
Car Company A has a range of 8, while Car Company B has a range of 15. Therefore, Car Company A has cars that are more consistent in highway fuel efficiency.
For Car Company A:
Range = Highest value - Lowest value
Highest value: 36
Lowest value: 28
Range = 36 - 28 = 8
For Car Company B:
Range = Highest value - Lowest value
Highest value: 40
Lowest value: 25
Range = 40 - 25 = 15
Comparing the range values:
Car Company A has a range of 8, while Car Company B has a range of 15. Therefore, Car Company A has cars that are more consistent in highway fuel efficiency.

41 39
38 38
46 40
41 42
37 41
40 40
To determine which restaurant has more consistent delivery times, we will calculate the range for each set of data. The smaller the range, the more consistent the data is.
For Restaurant 1:
Range = Highest value - Lowest value
Highest value: 46
Lowest value: 37
Range = 46 - 37 = 9
For Restaurant 2:
Range = Highest value - Lowest value
Highest value: 42
Lowest value: 37
Range = 42 - 37 = 5
Comparing the range values:
Restaurant 1 has a range of 9, while Restaurant 2 has a range of 5. Therefore, Restaurant 2 has more consistent delivery times.
For Restaurant 1:
Range = Highest value - Lowest value
Highest value: 46
Lowest value: 37
Range = 46 - 37 = 9
For Restaurant 2:
Range = Highest value - Lowest value
Highest value: 42
Lowest value: 37
Range = 42 - 37 = 5
Comparing the range values:
Restaurant 1 has a range of 9, while Restaurant 2 has a range of 5. Therefore, Restaurant 2 has more consistent delivery times.
