A manufacturer of paper used for packaging requires a minimum strength of 1700 g/cm2. To check on the quality of the paper, a random sample of 13 pieces of paper is selected each hour from the previous hour's production and a strength measurement is recorded for each. The standard deviation σ of the strength measurements, computed by pooling the sum of squares of deviations of many samples, is known to equal 170 g/cm2, and the strength measurements are normally distributed.
a) If the mean of the population of strength measurements is 1750 g/cm2, what is the approximate probability that, for a random sample of n = 13 test pieces of paper, x < 1700? (Round your answer to four decimal places.)
b) What value would you select for the mean paper strength μ in order that P(x < 1700) be equal to 0.001? (Round your answer to three decimal places.)

The authors of a paper titled "Age and Violent Content Labels Make Video Games Forbidden Fruits for Youth" carried out an experiment to determine if restrictive labels on video games actually increased the attractiveness of the game for young game players. Participants read a description of a new video game and were asked how much they wanted to play the game. The description also included an age rating. Some participants read the description with an age restrictive label of 7+,...
