(a) Construct a scatterplot of the right foot temperature (y) versus the left foot temperature (x). Foot temperatures: Foot ulcers are a common problem for people with diabetes. Higher skin temperatures on the foot indicatean increased risk of ulcers. In a study performed at the Colorado School of Mines, skin temperatures on both feet were measured,in degrees Fahrenheit, for 8 diabetic patients. The results are presented in the following table.

The table gives data on the price is charged for a beer (per ounce ) and for a hot dog at Major League Baseball stadiums. The correlation between the prices is r=0.21. What proportion of the variation in hot dog prices is explained by the least squares regression of hot dog prices on beer prices (per ounce)?
The figure plots the number of manatee deaths by boat versus the number of boats registered to Florida and thousands. There is a clear straight line pattern with a modest amount of scatter. The correlation between these variables is R equals 0.94. What percentage of the observed variation among the manatee deaths by boats is explained by the straight line relationship between manatee deaths and number of boats registered?

A patient is classified as having gestational diabetes if their average glucose level is above 140 milligrams per deciliter (mg/dl) one hour after a sugary drink is ingested. Rebecca's doctor is concerned that she may suffer from gestational diabetes. There is variation both in the actual glucose level and in the blood test that measures the level. Rebecca's measured glucose level one hour after ingesting the sugary drink varies according to the Normal distribution with μ=140+5 mg/dl and σ=5+1 mg/dl. Using the Central Limit Theorem, determine the probability of Rebecca being diagnosed with gestational diabetes if her glucose level is measured: Once? n=5+2 times n=5+4 times Comment on the relationship between the probabilities observed in (a), (b), and (c). Explain, using concepts from lecture why this occurs and what it means in context.
Customers at a large department store rated their satisfaction with their purchases, on a scale from 1 (least satisfied) to 10 (most satisfied). The cost of their purchases was also recorded. To three decimal places, determine the correlation coefficient between rating and purchase amount spent. Then describe the strength and direction of the relationship.
We want to predict the selling price of a house in Newburg Park, Florida, based on the distance the house lies from the beach. Suppose that we're given the data in the table below. These data detail the distance from the beach (x, in miles) and the selling price (y, in thousands of dollars) for each of a sample of fifteen homes sold in Newburg Park in the past year. The data are plotted in the scatter plot in Figure 1. Also given is the product of the distance from the beach and the house price for each of the fifteen houses. (These products, written in the column labelled "xy", may aid in calculations.)
