1.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 box plots shown. The top one is labeled Males. Minimum at 1, Q1 at 3, median at 10.5, Q3 at 14, maximum at 21. The bottom box plot 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.
A. The females worked more than the males and the female Q^3 equals the top of the range
B. The spread and center are skewed due to the fourth quartile missing with the females.
C. There is a significant outlier at the low end for the females
D. The males have a high outlier, and the females have a low outier
I think its a

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

two box plots shown. The top one is labeled July. Minimum at 80, Q1 at 88, median at 96, Q3 at 103, maximum at 105. The bottom box plot is labeled August. 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?
A. The august high is above the July median. This makes it hard to know about the means
B. Both months have the same low temperature. This makes it hard to know about the means
C. Its unlikely, but possible that the july mean could be higher.
D. There is no way to tell what the means are
I think its a
1.The box plots below show student grades on the most recent exam compared to overall grades in the class:

two box plots shown. The top one is labeled Class. Minimum at 68, Q1 at 71, median at 84, Q3 at 89, maximum at 100. The bottom box plot is labeled Exam. Minimum at 55, Q1 at 76, median at 85, Q3 at 94, maximum at 100

Which of the following best describes the information about the medians?
A. The class and exam medians are almost the same
B. The exam median is much higher than the class median
C. The class and exam q^3 are the same, but the exam has the lowest median
D. The low outlier on exams pulls the median lower.
I think its d

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

two box plots shown. The top one is labeled Movies. Minimum at 60, Q1 at 65, median at 95, Q3 at 125, maximum at 150. The bottom box plot is labeled Basketball games. Minimum at 90, Q1 at 95, median at 125, Q3 at 145, maximum at 150.

Which of the following best describes how to measure the spread of the data?
A. The IQR is a better measure of spread for movies than it is for basketball games
B. The standard deviation is a better measure of spread for movies than it is for basketball games
C. The IQR is the best measurement of spread for games and movies.
D. The standard deviation is the best measurement of spread for games and movies
I think its d

For question 1, the correct answer is B. The spread and center are skewed due to the fourth quartile missing with the females. In the box plot for females, there is no maximum value shown, indicating that there might be outliers that are pushing the upper part of the data further out from the median. This affects the statistical measures of spread and center, as the missing upper values in the data will result in a skewed distribution and an incomplete representation of the spread.

For question 2, the correct answer is A. The August high is above the July median. This makes it hard to know about the means. The box plots provide information about the minimum, maximum, quartiles, and median, but do not directly provide information about the means. However, based on the information given, we can see that the highest value in August is above the median value in July, suggesting that the mean for August is likely to be higher than the mean for July.

For question 3, the correct answer is A. The class and exam medians are almost the same. The median is the measure of center that divides the data into two equal halves. Based on the information given in the box plots, the median for the class is 84, and the median for the exam is 85. These values are very close to each other, indicating that the medians for the class and the exam are almost the same.

For question 4, the correct answer is A. The IQR is a better measure of spread for movies than it is for basketball games. The interquartile range (IQR) is a measure of spread that shows the range between the first quartile (Q1) and the third quartile (Q3). In this case, the IQR for both movies and basketball games is the same (60), but since the range of values in the movie attendance is larger (from 60 to 150) compared to the range in basketball game attendance (from 90 to 150), the IQR is a better representation of the spread in the movie attendance data.
