A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 404 gram setting. It is believed that the machine is underfilling the bags. A 40 bag sample had a mean of 402 grams. Assume the population standard deviation is known to be 28. A level of significance of 0.02 will be used. Find the P-value of the test statistic. You may write the P-value as a range using interval notation, or as a decimal value rounded to four decimal places.

A particular fruit’s weights are normally distributed, with a mean of 395 grams and a standard deviation of 29 grams. The heaviest 18% of fruits weigh more than how many grams? Give your answer to the nearest gram.

A successful basketball player has a height of 6 feet 11 ​inches, or 211 cm. Based on statistics from a data​ set, his height converts to the z score of 5.17. How many standard deviations is his height above the​ mean?
