2) The Easy Online Store's product variant population, with a mean of 1,250 and a standard deviation of 400, is known to be highly skewed to the right. If a random sample of 64 product variants is selected from the population, what is the probability that the sample mean will be less than 1,325? 1) Sector 6 Energy has sixteen employees working in procurement (considered the population) and their number of years of experience working with the firm are given in the table below. 10 10 5 14 18 19 7 20 10 14 8 2 10 3 2 10 a) Calculate the population mean. b) A simple random sample of five values (i.e., of five employees working in procurement) from the population in a) is selected and is given in the table below. Sumis 5 10 20 2 3 Calculate the mean of this sample. c) Based on the results in a) and b), calculate the sampling error for the sample mean.
