The director of a local Parks and Recreation department is interested in the number of hours kids spend outside each week. She surveys a group of 19 kids in her town and asks them how many hours they spent outside last week. Her results follow. What is the range of the dataset?
{0,10,15,4,70,15,18,20,6,8,10,12,15,18,20,2,50,40,10}
(1 point)
The range of the dataset of number of hours spent outside by the kids that the director surveyed is
hours.
The range of the dataset is the difference between the largest and smallest values.
Largest value: 70
Smallest value: 0
Range = 70 - 0 = 70
Therefore, the range of the dataset is 70 hours.

To find the range of the data shown in the table, we need to determine the difference between the maximum and minimum number of pairs of shoes owned by the 6th graders.
From the table:
- The minimum number of pairs of shoes owned is 2
- The maximum number of pairs of shoes owned is 10
Range = Maximum - Minimum
Range = 10 - 2
Range = 8
Therefore, the range for the number of pairs of shoes owned by the 6th graders Michael surveyed is 8 pairs of shoes.
Yasmine works as a server in a restaurant and earns different amounts in tips each night. Her range of earnings in tips over the course of 8 nights of work is $86.33. Her tip earnings are listed in order from least to greatest, with one missing:
$10.45, $20.50, $35.80, $38.10, $40.87, $45.90, $79.60, _______
What tip earnings value is missing?(1 point)
The value of the missing tip earnings is $
.
To find the missing tip earnings value, we first need to calculate the total range of earnings for 8 nights.
Given that the range of earnings is $86.33, and the smallest value is $10.45, the largest value can be found by adding the range to the smallest value:
Smallest value: $10.45
Range: $86.33
Largest value = Smallest value + Range
Largest value = $10.45 + $86.33
Largest value = $96.78
Now, we compare this calculated largest value with the listed tip earnings:
Given tip earnings in order: $10.45, $20.50, $35.80, $38.10, $40.87, $45.90, $79.60, $96.78
Therefore, the missing value in the list is $96.78.
Aziz wonders how many pieces of pizza people tend to eat at a pizza party. He surveys 11 people at the end of a pizza party and asks them how many pieces of pizza they ate. A list of his results follows. Find and interpret the mode of his data.
Number of Pieces of Pizza Eaten: 6, 2, 1, 2, 4, 5, 2, 2, 4, 6, 7(1 point)
Responses
The mode for number of pieces of pizza eaten is 4. This means about half of people ate more than 4 pieces of pizza and about half of people ate fewer than 4 pieces of pizza.
The mode for number of pieces of pizza eaten is 4. This means about half of people ate more than 4 pieces of pizza and about half of people ate fewer than 4 pieces of pizza.
The mode for number of pieces of pizza eaten is 2. This means that the majority of people ate 2 pieces of pizza.
The mode for number of pieces of pizza eaten is 2. This means that the majority of people ate 2 pieces of pizza.
There is no mode. This means there is no number of pieces of pizza that was eaten most often.
There is no mode. This means there is no number of pieces of pizza that was eaten most often.
The mode for number of pieces of pizza eaten is 2. This means more people ate 2 pieces of pizza than any other number of pieces of pizza.
The mode is the number that appears most frequently in a set of data. In this case, the data set is as follows:
6, 2, 1, 2, 4, 5, 2, 2, 4, 6, 7
From the data set, the number 2 appears three times, which is more frequent than any other number. Therefore, the mode for the number of pieces of pizza eaten is 2.
Interpreting the mode, it means that more people ate 2 pieces of pizza than any other number of pieces of pizza.

To find the mode of the number of siblings for the 6th graders that Kaylen surveyed, we need to determine the number of siblings that appears most frequently in the data set provided in the table.
From the table:
- Number of 6th graders with 0 siblings: 3
- Number of 6th graders with 1 sibling: 12
- Number of 6th graders with 2 siblings: 5
- Number of 6th graders with 3 siblings: 2
- Number of 6th graders with 4 siblings: 0
- Number of 6th graders with 5 siblings: 2
Since the number of 6th graders with 1 sibling (12 students) is the highest, the mode of the number of siblings for the 6th graders that Kaylen surveyed is 1 sibling.
Therefore, the correct response is:
1 sibling
