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 0.053 0.044 0.051 0.056 0.044 0.058 0.048 0.053 a. Is there evidence of non-normality? O No OYes *** 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.)
