The mean weight of all 20-year-old women in a certain region is 130 pounds. A random sample of 50 vegetarian women in the region who are 20 years old showed asample mean of 124 pounds with a standard deviation of 15 pounds. The women's measurements were independent of each other. Complete parts (a) through (c)below.a. Determine whether the mean weight for 20-year old vegetarian women in the region is significantly less than 130, using a significance level of 0.05.Which of the following correctly states Ho and Ha?O A.

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.
