An Excel assignment counts for 0-10 points. The scores in a class of 12 students are recorded as follows:1 5 5 6 7 7 8 8 8 9 10 10 What is the deviation of the score 10 from the mean in 13a (recall that this involves a subtraction of the mean from the particular score)? I think I got answer but want to check.

Consider the data from the Anthropology 105 class. The mean for women is 64.33 in and the standard deviation is 2.64 in. The average height of men in the US is approximately 5ft 10in. What proportion of women represented here are shorter than the average man?

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.
