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 ratesare shown below.0.044 0.040 0.054 0.044 0.050 0.055 0.044 0.059 0.047 0.054 pa. 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?YesNob. A minimum variance unbiased point estimate of the population mean iscubic centimeters per second.(Round to four decimal places as needed.)c. A point estimate of the variance of the sample mean iscubic centimeters per second.(Round to six decimal places as needed.)

The actual volumes of quart-size jars of Hellmann's mayonnaise are uniformly distributed from 31.47 to 32.47 fluid ounces. Find the standard deviation in volumes of quart-size Hellmann's mayonnaise jars (in fluid ounces). NOTE: There are 32 fluid ounces in a quart.
In an Omani factory, a machine that produces "W-product" has been set so that the true average diameter of the "W-product" it produces is 0.602 in. If its diameter is within 0.04 in. of this target value, this is acceptable. Suppose, however, that the setting has changed during the course of production, so that the products have normally distributed diameters with mean value 0.601 in. and standard deviation 0.002 in. What percentage of the "W-product" produced will not be acceptable

In an attempt to develop a model of wine quality as judged by wine experts, data on alcohol content and wine quality was collected from variants of a particular wine. From a sample of 12 wines, a model was created using the percentages of alcohol to predict wine quality. For those data, SSR = 18,858 and SST = 29,285. Use this information to complete parts (a) through (c) below. a. Determine the coefficient of determination, r², and interpret its meaning. 2² = (Round to three decimal places as needed.) Interpret the meaning of r². It means that% of the variation in (Round to one decimal place as needed.) b. Determine the standard error of the estimate.
