A soccer team sold coupon cards to raise money for new uniforms. One player was also a statistics student and kept track of how many cards she sold while out selling on a Saturday. Here are the data she recorded. Which of the following is the correct interpretation of the standard deviation?

The standard deviation is about 2.32 cards. The number of cards sold by this student typically varies by about 2.32 cards from the mean.

The standard deviation is about 5.38 cards. The number of cards sold by this student typically varies by about 5.38 cards from the mean.

The standard deviation is about 2.32 cards. The number of cards sold by this student typically varies by about 2.32 cards from the median.

The standard deviation is about 5.38 cards. The number of cards sold by this student typically varies by about 5.38 cards from the median.

A soccer team sold coupon cards to raise money for new uniforms. One player was also a statistics student and kept track of how many cards she sold while out selling on a Saturday. Here are the data she recorded. Which of the following is the correct interpretation of the IQR?

The IQR is 4 cards. The range of the middle half of cards sold by this player is 4 cards.

The IQR is 2 cards. The range of the lower half of cards sold by this player is 2 cards.

The IQR is 4 cards. The range of the lower half of cards sold by this player is 4 cards.

The IQR is 2 cards. The range of the middle half of cards sold by this player is 2 cards.

The following boxplots summarize data on carbon dioxide emissions data (measured in grams per mile) for 30 randomly selected vehicles from the 2016 model year. Which of the following is a correct comparison of the distributions for highway and city carbon dioxide emissions?

Both distributions are roughly symmetric. City driving tends to have higher carbon dioxide emissions (median = 450) than highway driving (median = 350). Because of the larger IQR, there is more variation in city driving than highway. There is one high outlier in the highway driving distribution while there are no outliers in the city driving distribution.

The city driving distribution is roughly symmetric, while the highway driving distribution is skewed to the right. City driving tends to have higher carbon dioxide emissions (median = 450) than highway driving (median = 350). Because of the larger IQR, There is more variation in city driving than highway. There is one high outlier in the highway driving distribution while there are no outliers in the city driving distribution.

Both distributions are roughly symmetric. City driving tends to have higher carbon dioxide emissions (median = 450) than highway driving (median = 350). Because of the smaller IQR, there is more variation in highway driving than highway. There is one high outlier in the highway driving distribution while there are no outliers in the city driving distribution.

Both distributions are roughly symmetric. City driving tends to have lower carbon dioxide emissions (median = 350) than highway driving (median = 450). Because of the larger IQR, there is more variation in city driving than highway. There is one high outlier in the highway driving distribution while there are no outliers in the city driving distribution.

Here are summary statistics that describe the distribution of the number of steps taken by a group of teachers on a randomly selected school day as recorded by a Fitbit. Which of the following responses provides the correct z-score and z-score interpretation for a teacher who took 11458 steps?

z = 1.057. This teacher’s steps for the day were 1.057 standard deviations above the mean of 10321 steps.

z = -1.057. This teacher’s steps for the day were 1.057 standard deviations below the mean of 10321 steps.

z = 1.057. This teacher’s steps for the day were within 1.057 standard deviations of the mean of 10321 steps.

A statistics instructor asked 15 students to record their heart rate while they were sitting at their desks. Here are their heart rates in beats per minute (bpm): 47, 55, 60, 60, 61, 62, 68, 70, 74, 76, 80, 88, 90, 96, 100 Find and interpret the percentile for the student whose heart rate was 90 bpm.

The 80th percentile. 80% of the students in the class had a heart rate lower than this particular student.

The 80th percentile. 80% of the students in the class had a heart rate higher than this particular student.

The 20th percentile. 20% of the students in the class had a heart rate higher than this particular student.

The 86.7th percentile. 86.7% of the students in the class had a heart rate lower than this particular student.
