Answer 2

The box plots show the average daily temperatures in July and August for a U.S. city:

two bar graphs shown. The top one is labeled July. Minimum at 80, Q1 at 88, median at 96, Q3 at 103, maximum at 105. The bottom bar graph is labeled August games. Minimum at 80, Q1 at 82, median at 84, Q3 at 90, maximum at 100

What can you tell about the means for these two months?

The August high is above the July median. This makes it hard to know about the means.

Both months have the same low temperature. This makes it hard to know about the means.

It is unlikely, but possible that the July mean could be higher.

There is no way to tell what the means are.





Question 2 (Multiple Choice Worth 1 points)

[06.02]

The box plots show student grades on the most recent exam compared to overall grades in the class:

two bar graphs shown. The top one is labeled Class. Minimum at 70, Q1 at 74, median at 83, Q3 at 92, maximum at 100. The bottom bar graph is labeled Exam. Minimum at 60, Q1 at 81, median at 87, Q3 at 91, maximum at 95.

Which of the following best describes the information about the medians?

The exam outlier at 60 makes the IQR narrower and the median higher.

The class data is more evenly spread, which pulls its median down.

The class median is lower than the exam median.

The class Q3 is higher than the exam Q3.





Question 3 (Multiple Choice Worth 1 points)

[06.02]

Male and female high school students reported how many hours they worked each week in summer jobs. The data is represented in the following box plots:

two bar graphs shown. The top one is labeled Males. Minimum at 0, Q1 at 1, median at 20, Q3 at 25, maximum at 50. The bottom bar graph is labeled Females. Minimum at 0, Q1 at 5, median at 6, Q3 at 10, maximum at 18

Identify any values of data that might affect the statistical measures of spread and center.

The females worked less than the males, and the female median is close to Q1.

There is a significant outlier at the high end for the males.

There are significant outliers at the high ends of both the males and the females.

Both graphs have the required quartiles.

Which of the choices below best describes how to measure the spread of this data?
Both spreads are best described with the IQR.

Both spreads are best described with the standard deviation.

The college spread is best described by the IQR. The high school spread is best described by the standard deviation.

The college spread is best described by the standard deviation. The high school spread is best described by the IQR.

Which of the choices below best describes how to measure the center of this data?
Both centers are best described with the mean.

Both centers are best described with the median.

The Rome data center is best described by the mean. The New York data center is best described by the median.

The Rome data center is best described by the median. The New York data center is best described by the mean.





Question 6 (Multiple Choice Worth 1 points)

[06.02]

The table shows data from a survey about the number of times families travel by car or taxi during an average week. The families are either from a rural town (population under 5,000) or a large city (population over 1 million):

40 30

Which of the choices below best describes how to measure the center of this data?
Both centers are best described with the mean.

Both centers are best described with the median.

The country data center is best described by the mean. The city data center is best described by the median.

The country data center is best described by the median. The city data center is best described by the mean.





Question 7 (Multiple Choice Worth 1 points)

[06.02]

The box plots show attendance at a local movie theater and high school basketball games:

two bar graphs shown. The top one is labeled Movies. Minimum at 100, Q1 at 130, median at 165, Q3 at 185, maximum at 200. The bottom bar graph is labeled Basketball games. Minimum at 135, Q1 at 225, median at 248, Q3 at 275, maximum at 300.

Which of the following best describes how to measure the spread of the data?

The IQR is a better measure of spread for movies than it is for basketball games.

The standard deviation is a better measure of spread for movies than it is for basketball games.

The IQR is the best measurement of spread for games and movies.

The standard deviation is the best measurement of spread for games and movies.





Question 8 (Multiple Choice Worth 1 points)

95 88
92 82
92 78
88 78
85 65
75 60

Which data set has the largest IQR?
Mid-term exams

Final exams

They have the same IQR.

There is not enough information.





Question 9 (Multiple Choice Worth 1 points)

[06.02]

The box plots show male and female grades in a U.S. history class:

two bar graphs shown. The top one is labeled Male. Minimum at 70, Q1 at 82, median at 88, Q3 at 95. The bottom bar graph is labeled Female. Minimum at 75, Q1 at 78, Q3 at 90, maximum at 92.

Which of the following best describes the information about the interquartile ranges?

The female interquartile range cannot be known because only three quartiles are showing.

The male interquartile range cannot be known because the fourth quartile is missing.

The male interquartile range is larger due to the size of the first quartile.

The two interquartile ranges are about the same size.





Question 10 (Multiple Choice Worth 1 points)

[06.02]

The table shows data from a survey about the amount of time high school students spent reading and the amount of time spent watching videos each week (without reading):



Reading

Video

4 4
4 5
5 6
5 8
5 9
6 10
7 11
8 12
8 14
9 25

Which response best describes outliers in these data sets?
Neither data set has suspected outliers.

The range of data is too small to identify outliers.

Video has a suspected outlier in the 25-hour value.

The 25-hour value for video does not pass the outlier test of 1.5 • (IQR) + Q3.

Answer 35

K142, are you from israel?

Answer 36

for the first u need to you just add it all up and divide by the number of the amount of figures? I would say that the August mean is probably going to be greater than the July mean.

It's difficult to understand what exactly you're aasking for tho.
