Mathematics: Astate meat inspector in iowa has been given theassignment of estimating the mean nt weight of packagers of groundchuck labeled 3 pounds. of course, he realizes that the weightscannot be precisely 3 pounds. a sample of 36 packages revealsthe mean weight to be 3.01 pounds, with a standard deviation of0.03 pounds. a. what is the estimated population mean? b. determine a 95 percent confidence interval for thepopulation mean.

(a) μ = 3.01 pounds

(b) 2.99985 to 3.02015 pounds

Step-by-step explanation:

a) The estimate population mean (μ) is given by the point estimate mean found in the sample, which is 3.01 pounds.

μ = 3.01 pounds.

b) At a 95% confidence interval, with n=36, z= 2.03 and the confidence interval is given by:

$x\pm z*\frac{s}{\sqrt n}\\3.01\pm 2.03\frac{0.03}{\sqrt 36}\\2.99985\ to\ 3.02015\ pounds$
