A supplier to automobile manufacturers wants to be sure that the leak rate (in cubic centimeters per second) of transmission oil coolers (TOCS) meets the established specification limits. A random sample of 10 TOCS is tested, and the leak rates are shown below. 0.044 0.040 0.054 0.044 0.050 0.055 0.044 0.059 0.047 0.054 O a. Is there evidence that the data are not normally distributed? b. Find a minimum variance unbiased point estimate of the population mean. c. Use an unbiased estimation procedure to find a point estimate of the variance of the sample mean. a. Is there evidence of non-normality? O Yes O No b. A minimum variance unbiased point estimate of the population mean is cubic centimeters per second. (Round to four decimal places as needed.) c. A point estimate of the variance of the sample mean is cubic centimeters per second. (Round to six decimal places as needed.)
