The following Minitab display gives information regarding the relationship between the body weight of a child (in kilograms) and the metabolic rate of the child (in 100 kcal/ 24 hr).
| Predictor | Coef | SE Coef | T | P |
| Constant | 0.8435 | 0.4148 | 2.06 | 0.84 |
| Weight | 0.41456 | 0.02978 | 13.52 | 0.000 |
| S = 0.517508 | R-Sq = 97.6% |
(a) Write out the least-squares equation.
| = | + x |
(b) For each 1 kilogram increase in weight, how much does the
metabolic rate of a child increase? (Use 5 decimal places.)
(c) What is the value of the correlation coefficient r?
(Use 3 decimal places.)

4) The correlation coefficient r is a sample statistic. What
does it tell us about the value of the population correlation
coefficient ρ (Greek letter rho)? You do not know how to build the
formal structure of hypothesis tests of ρ yet. However, there is a
quick way to determine if the sample evidence based on ρ is strong
enough to conclude that there is some population correlation
between the variables. In other words, we can use the value of...

We use the form y hat = a + bx for the least-squares line. In
some computer printouts, the least-squares equation is not given
directly. Instead, the value of the constant a is given, and the
coefficient b of the explanatory or predictor variable is
displayed. Sometimes a is referred to as the constant, and
sometimes as the intercept. Data from Climatology Report No. 77-3
of the Department of Atmospheric Science, Colorado State
University, showed the following relationship between elevation...

For a sample of 116 college students, the relationship between
the reported hours of sleep during the previous 24 hours and the
reported hours of study during the same period was studied. Data
for y = hours of sleep the previous day and x =
hours of studying the previous day for n = 116 college
students were computed. Some regression results for those data are
shown in the following table.
