A data set of 4 observations for Concession Sales per person at a theater and Minutes before the movie begins results in the estimated regression model Modifying Above Sales with caretSales=4.4+0.266 Minutes. The standard error of the regression slope is 0.0452

Complete parts a through d below.

a) Compute the value of thet-statistic to test if there is a significant relationship between Sales and Minutes. What are the hypotheses for thistest?

Find the value of thet-statistic. (Round to three decimal places as needed)

b) What are the degrees of freedom associated with thet-statistic? (Type a whole number)

c) What is theP-value associated with thet-statistic? (Round to three decimal places as needed)

d) At =0.05, can you reject the standard null hypothesis for theslope? Explain.
