OECtonS I. 1 10 2.5 (Must submit written work to Canvas!) This Question: 3 pts 35 of 36 (32 complete) The life spans of a species of fruit fly have a bell-shaped distribution, with a mean of 36 days and a standard deviation of 4 days. (a) The life spans of three randomly selected fruit flies are 39 days, 35 days, and 45 days. Find the z-score that corresponds to each life span. Determine whether any of these life spans are unusual. (b) The life spans of three randomly selected fruit flies are 28 days, 44 days, and 32 days. Using the Empirical Rule, find the percentile that corresponds to each life span. (a) The z-score corresponding a life span of 39 days is. (Type an integer or a decimal rounded to two decimal places as needed.) The z-score corresponding a life span of 35 days is (Type an integer or a decimal rounded to two decimal places as needed.) The z-score corresponding a life span of 45 days is. (Type an integer or a decimal rounded to two decimal places as needed.) Select all of the life spans that are unusual. A. 39 days B. 45 days C. 35 days D. None of the life spans are unusual. (b) Determine the percentiles using the Empirical Rule. The 28 day fruit fly corresponds to the th percentile. The 44 day fruit fly corresponds to the th percentile. The 32 day fruit fly corresponds to the th percentile. (Type an integer or a decimal.)
