The life spans of a species of fruit fly have a bell-shaped distribution, with a mean of 34 days and a standard deviation of 5 days. (a) The life spans of three randomly selected fruit flies are 38 days, 32 days, and 46 days. Find the z-score that corresponds to each life span. Determine whether an of these life spans are unusual. (b) The life spans of three randomly selected fruit flies are 39 days, 44 days, and 24 days. Using the Empirical Rule, find the percentile that corresponds to each life span. (a) The z-score corresponding a life span of 38 days is (Type an integer or a decimal rounded to two decimal places as needed.) The z-score corresponding a life span of 32 days is (Type an integer or a decimal rounded to two decimal places as needed.) The z-score corresponding a life span of 46 days is (Type an integer or a decimal rounded to two decimal places as needed.) Select all of the life spans that are unusual. O A. 46 days O B. 38 days

Question
The life spans of a species of fruit fly have a bell-shaped distribution, with a mean of 34 days and a standard deviation of 5 days.
(a) The life spans of three randomly selected fruit flies are 38 days, 32 days, and 46 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 39 days, 44 days, and 24 days. Using the Empirical Rule, find the percentile that corresponds to each life
span.
(a) The z-score corresponding a life span of 38 days is
(Type an integer or a decimal rounded to two decimal places as needed.)
The z-score corresponding a life span of 32 days is
(Type an integer or a decimal rounded to two decimal places as needed.)
The z-score corresponding a life span of 46 days is
(Type an integer or a decimal rounded to two decimal places as needed.)
Select all of the life spans that are unusual.
O A. 46 days
O B. 38 days
O C. 32 days
