A trainer wishes to find out if there is a relationship between the number of miles walked per week and the weight of a person. The data for the sample are shown:
Miles Walked, x: 15 20 3 12 17 8
Weight (lbs.), y: 147 106 210 160 122 165
a) Compute the value of the correlation coefficient.
b) Find the equation of the regression line.
c) Find y’ (the weight) when x = 11. (Someone walks 11 miles).

The average number of miles a person drives per day is 24. A
researcher wishes to see if people over age 60 drive less than 24
miles per day. She selects a random sample of27 drivers over the
age of 60 and finds that the mean number of miles driven is 22.2.
The population standard deviation is miles 3.7. At a=0.05, is there
sufficient evidence that those drivers over 60 years old drive less
than 24 miles per day on...

A company want to find out if there is a linear relationship
between indirect labor expense (ILE), in dollars, and direct labor
hours (DLH). Data for direct labor hours and indirect labor expense
for 25 months are given. Based on the data in the table below, is
there a significant linear relationship between Direct Labor Hours
and the Indirect Labor Expense?

Suppose that an arborist wishes to see if there is a
relationship between the heights of baobabs in Madagascar forests
and their diameters. He selects 10 baobabs at random from the
forest and measures their heights and diameters. To ensure
consistent measurements, he records the diameters around the tree
from a height of 1.4 metres above the ground.
