If p= 0, then the two variables under consideration are linearly __
Short Answer
p= 0 implies that the two variables are linearly uncorrelated.

Birdies and Score. How important are birdies (a score of one-under par on a given hole) in determining the final total score of a woman golfer? From the U.S. Women's Open website, we obtained data on number of birdies during a tournament and the final score for women golfers. The data are presented on the Weiss Stats site.
a. obtain and interpret the standard error of the estimate.
b. obtain a residual plot and a normal probability plot of the residuals.
c. decide whether you can reasonably consider Assumptions for regression inferences met by the two variables under consideration.
14.75 High and Low Temperature. The data from Exercise for average high and low temperatures in January for a random sample of cities are on the WeissStats site.
a. Decide whether you can reasonably apply the regression -test. If so, then also do part .
b. Decide, at the significance level, whether the data provide sufficient evidence to conclude that the predictor variable is useful for predicting the response variable.
In Exercises 14.48-14.57, we repeat the information from Exercises 14.12-14.21.
a. Decide, at the lore significance level, whether the data provide sufficient evidence to conclude that \(x\) is useful for predicting y.
b. Find a 90rk confidence interval for the slope of the population regression line.


Following are the age and price data for corvettes, use
presuming that the assumption for regression inference are met, decide at the specified significance level whether the data provide sufficient evidence to conclude that the predictor variable is useful for providing the response variable.
we repeat the data and provide the sample regression creations
a. Determine the standard error of the estimate
b. Construct of residual plot.
c. Construct a nommal probability plot of the residuals.
| x | 2 | 4 | 3 |
| y | 3 | 5 | 7 |
