45} At Chevy. they want to test two new tire treads to see if one has a quicker stopping time than the other in snow. They perform two separate observations. The first tire treads are put on a vehicle and once the vehicle obtains a speed of 3!} mph while traveling in the snow. the brakes are applied and the time it takes to stop is recorded. They repeat this l times. The tires are then switched out and the same ob servation is applied to the second set of tires. The boxplots below show the distribution of times for each tire tread {Tread A and Tread B} are shown below. 5 5.5 s 15.5 T 75 S 3.5 9' 9.5 1CI l 11 Stopping Times Which of the following is an accurate comparison of the distributions? (A) Tread A is normally distributed while Tread E is uniform. [B] Tread A has a smaller median and IQR than Tread E. {C} Tread A has a larger mean and range than Tread B. {D} Tread A has at least one outlier and Tread E has a larger median. {E} Tread A. is symmetric and has a larger range than Tread E. 4?} The distribution of your favorite bag ofTakis has a mean weight of El} oz with a standard deviation of 0.35 or. You purchase a bag and determine that it is at the 40'3\" percentile in your distribution. How does your bag comp are to the mean weight of all Talci bags? (A) {1.35 oz less than the mean [B] 5.35 or greater than the mean {C} HURTS oz less than the mean {D} HUETS oz greater than the mean {E} There is not enough information to answer the question 48) A data set has the following values: 1, 2, 3, 4, 5, 6, 7, 8 Which of the following summary statistics is the largest? (A) x (B) Q1 (C) Sx (D) n (E) IQR 49) A random sample of 22 students was taken and their GPA was recorded, along with data on if they have or are currently in AP Chemistry. The data is displayed in the stemplot below. AP Chemistry No AP Chemistry 2 1 4 5 5 6 7 8 9 8 4 1 30 2 5 6 8 6 5 20 042 GPA KEY: 418 = 4.8 Which of the following is true about the range and standard deviation of these distributions? (A) "AP Chemistry" group has a larger range and standard deviation. (B) "No AP Chemistry" group has a larger range and standard deviation. (C) "AP Chemistry" group has the larger range, but "No AP Chemistry" group has the larger standard deviation. (D) "No AP Chemistry" group has the larger range, but "AP Chemistry" group has the larger standard deviation. (E) The ranges for both groups are the same, but we cannot determine the standard deviation from the stemplot.50) The following histogram shows the ages of people who are applying for a teaching position at your school. 4 Frequency 2- 0- 22 24 26 25 30 32 34 36 Ages Which of the following statements is correct? (A) The median is between 24 and 26 (B) The mean is less than the median (C) The distribution is left skewed (D) The maximum age is 36 years old (E) None of the above statements is correct
