We wish to estimate the mean weight of all men from a country with a 90% confidence level and a margin of error 2.6 lb. Assume that the population standard deviation is known to be 15.08 lb. A) Read carefully the text and provide each of the following: The error is E= , the population standard deviation o= , the confidence level is CL = %. B) Find the critical value za2 which is the zscore for which the right area is ?2. za2= (Hint: keep in mind that a=1−the confidence level) C) How large should the sample size be?
