A survey found that women's heights are normally distributed with mean 62.1 in. and standard deviation 3.2 in. The survey also found that men's heights are normallydistributed with mean 69.9 in. and standard deviation 3.4 in. Most of the live characters employed at an amusement park have height requirements of a minimum of 56in. and a maximum of 62 in. Complete parts (a) and (b) below.a. Find the percentage of men meeting the height requirement. What does the result suggest about the genders of the people who are employed as characters at theamusement park?The percentage of men who meet the height requirement is %.

In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.The artifact frequency for an excavation of a kiva in Bandelier National Monument gave the following information.
