Education The following ordered pairs give the entrance exam scores x and the grade-point averages y after 1 year of college for 10 students. (75, 2.3), (82, 3.0), (90, 3.6), (65, 2.0), (70, 2.1), (88,3.5), (93, 3.9), (69,2.0), (80, 2.8), (85, 3.3) (a))Create a scatter plot of the data. Does the relationship between x and y appear to be approximately linear? Explain.

A medical statistician wanted to examine the relationship between the amount of sunshine (x) and incidence of skin cancer (v). As an experiment he found the number of skin cancers detected per 100,000 of population and the average daily sunshine in eight counties around the country. These data are shown below. 2. Average Daily Sunshine Skin Cancer per 100,000 6: 7 S 6 4 9: 12: 15: 10 3 ?: 11 5 Draw a scatter plot and find the least squares regression line. ỹ =

When creating the dot plot, how are multiple data points for a single score displayed? a. A larger size dot is used; the size of the dot is directly proportional to the number of data points. b. More than one dot is used; dots are placed side by side creating a wider interval. c. A dot plot is innappropriate when multiple data points exist for a single score. d. Multiple dots, representing each data point, are replaced on top of one another.

(b) (i) Describe the skewness of the above histogram. (ii) Describe the shape of the above histogram in term of the number of mode(s).“
