1) hypothesis that the mean age al first marriage for women in Texas is less than 21.3. In a sample of 58 Texas wornen, he finds that the average age is 23.7 with a standard deviation of 4.0
Calculate the test statistic to two decimal places
2) A theoreme that allows us to use the normal probability distribution to approximate the sampling distribution of the sample mean whenever the sample size, n is large enough is
a)approximation theorem
b)central limit theorem
c)normal probability theorem
d)central continuity theorem
3) it is known that the standard deviation of the process that produces bottles of perfume is 0.22 ounces, while the mean is 4 ounces. The company producing the perfume ships the
bottes in cases of 121 to a wholesaler store, which then calculates the mean fill of these bottles. Assuming that a case of 121 bottles represents a random sample from the process
that makes the perfume, find the probability that the sample mean will be below 3.98 ounces. Round your answer to three (3) decimal places, and choose the closest answer.
