Solve the below question

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 specication 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 Ci 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 nd a point estimate of the variance of the sample mean. a. Is there evidence of nonnormality.) 0 Yes 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.)
