question 17&18

Lorelai is opening her own inn and is figuring out how she should budget the money to increase revenue. A particular concern is about how the advertising budget affects the revenue from bookings at the inn. She decides to explore this relationship in her current work place the Independence Inn in the same town. The partial regression output below explores the relationship between advertising budget (per month) and revenue from bookings in the same month at the Independence Inn. 30000 Revenue [in dollars) 15000 5000 700 9000 10000 Advertising budget (in dollars) The regression line fitted for the above random sample is given by, Revenue = 5000 + 2.5"(Advertising budget) If on a particular month the amount of $4000 was put into advertising, can we use the regression line to predict the revenue for that month? Select one O a. No, because we cannot predict outside the range of the sampled data. O b. Yes, and the prediction is $15,000 O c. No, the scatterplot does not depict a linear relationship between the dependent and independent variables O d. Yes, and the prediction is $17,500 Which of the following is not an appropriate conclusion to draw from a P-value? Select one; a. We fail to reject the null hypothesis, O b. We have sufficient evidence to conclude that the alternate hypothesis is true. O c. We accept the null hypothesis. O d. We do not have sufficient evidence to conclude that the alternate hypothesis is true. O e. We reject the null hypothesis
