Answer 2

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 1, Q1 at 3, median at 10.5, Q3 at 24, maximum at 21. The bottom bar graph is labeled Females. Minimum at 0, Q1 at 15, median at 18, Q3 at 21, no maximum shown

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

The females worked more than the males, and the female Q3 equals the top of the range.
The spread and center are skewed due to the fourth quartile missing with the females.
There is a significant outlier at the low end for the females.
The males have a high outlier, and the females have a low outlier.

Answer 3

a

Answer 4

the female doesn't have a fourth quartile if you look at it

Answer 5

so that's wrong

Answer 6

yea it would be B

Answer 7

ok thank you

Answer 8

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 74, Q1 at 78, median at 85, Q3 at 93, maximum at 98. The bottom bar graph is labeled Exam. Minimum at 81, Q1 at 85, median at 93, Q3 at 96, maximum at 99.

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

The exam median is only 1-2 points higher than the class median.
The exam median is much higher than the class median.
The additional scores in the second quartile for the exam data make the median higher.
The narrower range for the exam data causes the median to be higher.

Answer 9

c

Answer 10

yes i believe that would be correct

Answer 11

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.

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.

Answer 30

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

two bar graphs shown. The top one is labeled January. Minimum at 0, Q1 at 10, median at 12, Q3 at 13, maximum at 16. The bottom bar graph is labeled December games. Minimum at 1, Q1 at 5, median at 18, Q3 at 25, maximum at 35

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

The mean for December is higher than January's mean.
It is almost certain that January's mean is higher.
There is no way of telling what the means are.
The narrow IQR for January causes its mean to be lower.

Answer 31

a

Answer 32

no you can't tell the mean

Answer 33

because they don't show all of the data

Answer 34

c then @Mehek14

Answer 35

42 38

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.

Answer 40

c

Answer 41

because the median for male is 91 and for females its 86
