The ages of the winners of a cycling tournament are approximately bell-shaped. The mean age is 28.9 years, with a standard deviation of 3.6 years. The winner in one recent year was 30 years old. (a) Transform the age to a z-Score. (b) Interpret the results. (c) Determine whether the age is unusual. (a) Transform the age to a z-score. (Type an integer or decimal rounded to two decimal as as needed.) (b) Interpret the results. An age of 30 is about standard deviation(s) (Type an integer or decimal rounded to two decimal places as needed.) V the mean. (c) Determine whether the age is unusual. Choose the correct answer below. O A. Yes, this value is unusual. AZ-Score outside of the range from -2 to 2 is unusual. O B. No, this value is not unusual. A Z-score between -2 and 2 is not unusual. OC. Yes, this value is unus z-score between -2 and 2 is unusual. COD. No, this value is nol unusual. Ascoe outside of the range from -2 to 2 is not unusual.

Use z scores to compare the given values. In a recent awards ceremony, the age of the winner for best actor was 28 and the age of the winner for best actress was 44. For all best actors, the mean age is 42.3 years and the standard deviation is 8.4 years. For all best actresses, the mean age is 33.3 years and the standard deviation is 10.7 years. (All ages are determined at the time of the awards ceremony.) Relative to their genders, who had the more extreme age when winning the award, the actor or the actress? Explain. Since the z score for the actor is z = and the z score for the actress is z=, the had the more extreme age. (Round to two decimal places.)
A successful basketball player has a height of 6 feet 11 inches, or 211 cm. Based on statistics from a data set, his height converts to the z score of 5.17. How many standard deviations is his height above the mean?

On an intelligence test, the mean number of raw items correct is 236 and the standard deviation is 39. What are the raw (actual) scores on the test for people with IQs of (a) 119, (b) 81, and (c)100? To do this problem, first figure the Z score for the particular IQ score; then use that Z score to find the raw score. Note that IQ scores have a mean of 100 and a standard deviation of 15. (a) What is the raw (actual) score on the test for people with an IQ of 119?
