This data was collected from the members of our class. I have tried to remove anything that would identify an individual. 1. What is the scale of each variable? 2. Construct a frequency table and chart showing the distribution across gender in this class. 3. Construct a cross tabulation with Gender in one direction and Height in the other direction. Group the height category into 5 groups. 4. Is there a difference in the age distribution across gender? 5. Give a summary of our class based on this data about our class.   Gender Height Year Born Male 76 1994 Male 72 1983 Female 65 1997 Male 68 1966 Female 67 1997 Male 70 1996 Male 71 1996 Male 73 1996 Male 72 1995 Male 71 1998 Male 73 1993 Female 66 1980 Female 62 1998 Male 76 1984 Female 70 1985 Female 62 1992 Female 62 1992 Male 73 1996 Female 68 1987 Male 60 1971 Female 60 1971 Male 60 1971 Male 74 1970 Male 77 1998 Male 77 1998 Male 68 1990 Female 64 1996 Male 80 1997 Male…

Identify any outliers. Choose the correct choice below. O A. There exists at least one outlier in the data set at (Use a comma to separate answers as needed.) OB. There are no outliers in the data set. 0 C

The attached plots were constructed using a sample of 272 observations. Each observation gives the elapsed time (in minutes) of an eruption of Old Faithful geyser in Yellowstone national park. a. Which graph is more appropriate for this data set? Explain your answer. b. Use the plots to describe the shape of the distribution of this data set. c. Are there are any potential outliers in this sample? Explain

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.
