Production output (i.e., number of parts) for a random sample of days from two different plants is shown below. Sample Size (n) 45 55 Sample Mean output (x-bar) 1,250 1,325 Sample Variance (s2) 625 676 What is the estimate of the standard deviation for the difference between the two means?
Suppose you are interested in measuring the amount of time on average it takes you to makeyour commute to school. You have estimated that the average time is 38.4 minutes with a standard deviation of 5.362 minutes. Over 12 random days, you measure your commute time. Assuming that your estimated parameters are correct and is normally distributed. Answer the following questions: (a) What is the distribution of the sample mean X¯?(b) What is the mean and standard deviation of the sample mean X¯?(c) What is the probability that the sample mean for sample size 12 will be greater than 36.19 minutes?
