A city planning department conducted a regression analysis to explore the relationship between the number of hotel rooms in a resort and the annual revenue generated (in millions of dollars).The regression equation obtained from the data of 55 resorts is revenue = 2.0 + 0.5 × rooms\text{revenue = 2.0 + 0.5 × rooms}.i. What is the best predicted annual revenue for a resort that has 100100 rooms?ii. Based on the regression model, do you think this prediction is likely to be accurate?

i. $$52 million\52$$\text{ million}ii. Yes, the prediction is only slightly beyond the range and follows the trend.

i. $$50 million\50$$\text{ million}ii. Yes, because 100100 rooms are within the data range.

i. $$50 million\50$$\text{ million} ii. No, because the equation does not apply to resorts.

i. $$52 million\52$$\text{ million}ii. No, predictions beyond 9090 rooms are completely unreliable.
