What is P value and how to get this?

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 gale: = 4.3 + 0.265 Minutes. The standard error of the regression slope is 0.0454. Complete parts a through d below. 2) Compute the value of the t-statistic to test if there is a signicant relationship between Sales and Minutes. What are the hypotheses for this test? H0: [31 = 0 HA: [51 # 0 Find the value of the t-statistic. t= 5.837 (Round to three decimal places as needed.) b) What are the degrees of freedom associated with the t-statistic? df = 2 (Type a whole number.) c) What is the P-velue associated with the t-statistic? Pvalue = (Round to three decimal places as needed.)
