a) The average height of sunflowers in a field is 64 in. with a standard deviation of 3.5 in. On a piece of paper, draw a normal curve forthe distribution, including the values on the horizontal axis at one, two, and three standard deviations from the mean. Describe yourdrawing in as much detail as possible, and explain how you came up with each of your labels.b) If there are 3,000 plants in the field, approximately how many will be taller than 71 in.? Explain how you got your answer.

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.
