The equation of the linear regression line is: ?yy^ = + xx (Please show your answers to two decimal places) Use the model to predict the amount of money spent by a customer who spends 18 minutes at the store.Dollars spent = (Please round your answer to the nearest whole number.)

A grocery store manager did a study to look at the relationship between the amount of time (in minutes) customers spend in the store and the amount of money (in dollars) they spend. The results of the survey are shown below. Time Elm-\"Ill\" mum 103 El- a. Find the correlation coefficient: r = [: Round to 2 decimal places. b. The null and alternative hypotheses for correlation are: The p-value is: [:] (Round to four decimal places) n . Use a level of significance of a = 0.05 to state the conclusion of the hypothesis test in the context of the stud . 0 There is statistically insignificant evidence to conclude that there is a correlation between the amount of time customers spend at the store and the amount of money that they spend at the store. Thus, the use of the regression line is not appropriate. 0 There is statistically insignificant evidence to conclude that a customer who spends more time at the store will spend more money than a customer who spends less time at the store. 0 There is statistically significant evidence to conclude that there is a correlation between the amount of time customers spend at the store and the amount of money that they spend at the store. Thus, the regression line is useful.
