Here is some information about the heights and weights of a random sample of 25 male students at a high school. Here are the scatter plot, the residual plot, a histogram of the residuals, and the regression analysis for the data we collected from them. Use this information to analyze the association between heights and weights. Use a 5% level of significance.

Perform a significance test and state your conclusion in context.

The population is male students at this high school- the parameter is the relationship between height and weight for male students at this school
The population is the 25 male students who were measured- the parameter is the relationship between height and weight for the 25 male students at this school

Ho:

Ha:

Choose the conditions which must be met:

Name the test:

Test Statistic

t =

The P-value is

less than alpha
greater than alpha

Make a decision:

Because our P-Value is less than alpha - we fail to reject the Ho.
Because our P-value is greater than alpha - we fail to reject the Ho.
Because our P-value is less than alpha - we reject the Ho.
Because our P-value is greater than alpha - we reject the Ho.

State the conclusion:
