Question
A)Test the claim, at the a = 0.10 level of significance, that a linear relation exists
between the two variables, for the data below, given that y-1.885x + 0.758.
Step 1) State the null and alternative hypotheses.
Step 2) Determine the critical value for the level of significance, a.
Step 3) Find the test statistic or P-value.
Step 4) Will the researcher reject the null hypothesis or do not the null hypothesis?
Step 5) Write the conclusion.
B) The regression line for the given data is y = -1.885x + 0.758. Determine the
residual of a data point for which x = 2 and y = -4.
C) Give a practical interpretation of the coefficient of determination, R2. Express R2
to the nearest whole percent.
