To estimate the mean number of days that an employees was absent from work last year, Hamilton Manufacturing took a random sample of 600 of its employees. the mean of the sample was 16.3. it is known that the population standard deviation is 5.1. the 95% confidence interval was therefore approxiamately 16.3 ± m. What is the width of the confidence interval?

Mrs. Gallas wanted to estimate the average weight of an Oreo cookie to determine if theaverage weight was less than advertised. She selected a random sample of 30 cookies andfound the weight of each cookie (in grams). The mean weight was = 11.1921 grams with astandard deviation of sx = 0.0817 grams.

Albert, a student of statistics, considered a random sample of the duration of 100 phone calls. He constructed the confidence interval with 95% confidence. Veronica selected her own random sample of 100 phone calls and constructed a confidence interval with 95% confidence. Is it possible that the confidence interval she obtained is different from the one Albert obtained? Explain why or why not. Suppose that they do not have information about the standard deviation of the population
