For the following Normal Distribution, X1 and X2 are equal to? 95% X1 X2 µ=4 o=2 In case the graph isn't clear, the shaded area of 95% is between X1 and X2. O and 8 -1 and 1 2 and 6 -2 and 10
Quantile Plot 09 77 74 85 80 81 17 18 Answer Refer to the data set below (body mass index of men) and determine whether the requirement of a normal distribution is satisfied. Assume that this requirement is loose in the sense that the population distribution need not be exactly normal, but it must be a distribution that is basically symmetric with only one mode. Is the requirement of a normal distribution satisfied? 19 20 1. Yes. The points in the normal quantile plot lie reasonably close to a straight line. 2. Yes. The points in the normal quantile plot exhibit some systematic pattern that is not a straight-line pattern. 3. No. The points in the normal quantile plot do not lie close to a straight line. 4. No. The histogram of the data is not bell shaped. There is also more than one outlier.

K A ski gondola carries skiers to the top of a mountain. Assume that weights of skiers are normally distributed with a mean of 187 lb and a standard deviation of 40 lb. The gondola has a stated capacity of 25 passengers, and the gondola is rated for a load limit of 3500 lb. Complete parts (a) through (d) below. a. Given that the gondola is rated for a load limit of 3500 lb, what is the maximum mean weight of the passengers if the gondola is filled to the stated capacity of 25 passengers? The maximum mean weight is lb. (Type an integer or a decimal. Do not round.) b. If the gondola is filled with 25 randomly selected skiers, what is the probability that their mean weight exceeds the value from part (a)? The probability is (Round to four decimal places as needed.) c. If the weight assumptions were revised so that the new capacity became 20 passengers and the gondola is filled with 20 randomly selected skiers, what is the probability that their mean weight exceeds 175 lb, which is the…
