Workers at a certain soda drink factory collected data on the volumes (in ounces) of a simple random sample of 1919 cans of the soda drink. those volumes have a mean of 12.19 oz and a standard deviation of 0.110.11 oz, and they appear to be from a normally distributed population. if the workers want the filling process to work so that almost all cans have volumes between 11.9611.96 oz and 12.6412.64 oz, the range rule of thumb can be used to estimate that the standard deviation should be less than 0.170.17 oz. use the sample data to test the claim that the population of volumes has a standard deviation less than 0.170.17 oz. use a 0.050.05 significance level. complete parts (a) through (d) below.

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
