No matter what the population looks like, those sample means will be roughly normally distributed given a reasonably large sample size (at least 30). Practice calculating the mean and standard deviation for the sampling distribution of a sample mean. Based on his interval, is it plausible that this part's average thickness agrees with the target value? No, it isn't. Find a test center location near you, or take the test at home. To me, this is incorrect. Based on this sample, which of the following is closest to a 90 % confidence interval for the mean price of gasoline that day in her state?
