25] The weight of a newborn baby deer {fawn} is 4 pounds with a standard deviation of 3 pounds. 1|Which of the followmg is true about the distribution of fawn weights\".l {A} The distribution is approximately Normal. because you are able to calculate the mean and standard deviation of the data. (B) The distribution is skewed to the left. since the least possible weight is less than 2 standard detiations astray om the mean. {C} The distribution is skewed to the right. since the least possible weight is less than 2 standard detiations away om the mean. {D} The distribution is approximately Normal. because one standard deviation above the mean and one standard deviation below the mean are still valid weights. {E} The distribution is approximately uniform. since the standard deviation is almost the same value as the mean. 2?) A statistician wallcs into the Chicago Public Library on a Sunday afternoon and records the number of boolrs the patrons of the library have in their possession, as well as their age group. The data is organized in the parallel boxplots below. :s -E!-T }_-_{ aha-e 3.: CI 0.5 l [.5 E 3.5 3. 3.5 4 4.5 5 5.5 fl Nu other of Books Which of the following must be true? (A) The age group of 132? has an outlier of I5 books. {13) The IQR of the under 13 group is the same as the IQR of the above 31" age group. {C} The proportion of people who have between 2 to 3 books in the under 13 group is the same as the proportion of people who have between 2 to 3 books in the above 3'? age group. [D] The 23 33" age group is more right skewed than the above 33" age group is. {E} The 13 2? age group has a smaller standard deviation than the 23 37' age group. 23) At a daycare, they have I5 kids: three 2 year olds. four 3 year olds. and 1 four year old. If another 4 year old enters the room. (A) the mean age will stay the same but the standard deviation will increase {B} the mean age will stay the same but the standard deviation will decrease {C} the mean age and the standard deviation will stay the same {ID the mean and the standard deviation will increase {E} the mean and the standard deviation will decrease 29) The histogram below shows an approximately normal distribution of the weights of adult German Shepherd dogs. 30.0% 25.0%- 20.0%- Relative Frequency 15.0% 10.0% 5.0% 0.0% 60 65 70 75 80 85 90 95 Weight (Ibs) What is the approximate mean and standard deviation? (A) u = 75, 0=5 B) u = 75, 6 = 10 C) u = 70, 0=5 D) u = 70, 6 = 10 (E) Cannot be determined from the information given 30) In your AP Statistics class, you have 8 students. The mean weight of these 8 students is 172 pounds. Seven of the students' weights are: 154, 189, 103, 127, 213, 155, and 160. Determine the weight of the remaining member. (A) 262 (B) 268 (C) 275 D) 103 (E) None of the above is correct
