Need help with d,f,g gsA 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 surveyare shown below.Time30 514 21 828 1894 77Money99237097 29a. Find the correlation coefficient: r0.93✓ Round to 2 decimal places.b. The null and alternative hypotheses for correlation are:Ho: P0H₁: p#08⁰OFThe p-value is:0.0020(Round to four decimal places)c. Use a level of significance of a = 0.05 to state the conclusion of the hypothesis test in the contextof the study.There is statistically insignificant evidence to conclude that a customer who spends more timeat the store will spend more money than a customer who spends less time at the store.vidence to conclude that there is a correlation between thethat they spend at the ngsOTd. 2e. Interpret ²(Round to two decimal places)There is a large variation in the amount of money that customers spend at the store, but if youonly look at customers who spend a fixed amount of time at the store, this variation onaverage is reduced by 87%.O Given any group that spends a fixed amount of time at the store, 87% of all of those customerswill spend the predicted amount of money at the store.O There is a 87% chance that the regression line will be a good predictor for the amount ofmoney spent at the store based on the time spent at the store.O 87% of all customers will spend the average amount of money at the store.f. The equation of the linear regression line is:y =(Please show your answers to two decimal places)g. Use the model to predict the amount of money spent by a customer who spends 16 minutes at thestore.Dollars spent =(Please round your answer to the nearest whole number.)h. Interpret the slope of the regression line in the context of the question:
