If a variable has a distribution that is bell-shaped with mean 15 and standard deviation 3, then according to the Empirical Rule, 68.0% of the data will lie between which values? (This is a reading assessment question. Be certain of your answer because you only get one attempt on this question.) According to the Empirical Rule, 68.0% of the data will lie between __ and __.

A particular population, for which the frequency curve is bell-shaped (normal), has a mean of μ=100 and a standard deviation of σ=18. For samples of size n=36 consider the sampling distribution of the sample mean ("xbar"). Note that {18\squareroot of 36) =3 and that 100±(1)(3)⟹97 to 103 100±(2)(3)⟹94 to 106 100±(3)(3)⟹91 to 109 According to the empirical rule, approximately _____ percent of samples of size 36 will produce a sample mean between 97 and 103.

A) The life spans of a species of fruit fly have a bell-shaped distribution, with a mean of 30 days and a standard deviation of 55 days. (a) The life spans of three randomly selected fruit flies are 32 days, 26 days, and 43 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 20 days, 40 days, and 35...
