Resorts & Spas, a magazine devoted to upscale vacations and accommodations, published its Reader's Choice List of the top 20 independent beachfront boutique hotels in the world. The data shown are the scores received by these hotels based on the results from Resorts & Spas' annual Readers' Choice Survey. Each score represents the percentage of respondents who rated a hotel as excellent or very good on one of three criteria (comfort, amenities, and in-house dining). An overall score was also reported and used to rank the hotels. The highest ranked hotel, the Muri Beach Odyssey, has an overall score of 94.3, the highest component of which is 97.7 for in-house dining. If required, round your answer to three decimal places.

(a)	Determine the estimated multiple linear regression equation that can be used to predict the overall score given the scores for comfort, amenities, and in-house dining.
	Let x1 represent Comfort.
	Let x2 represent Amenities.
	Let x3 represent In-House Dining.
	= + x1 + x2 + x3?
(b)	Use the t test to determine the significance of each independent variable. What is the conclusion for each test at the 0.01 level of significance? If your answer is zero, enter 0.
	The p-value associated with the estimated regression parameter b1 is _? . Because this p-value is - Select your answer -less or greater(Item 6) than the level of significance, we - Select your answer -reject or do not reject(Item 7) the hypothesis that 1 = 0. We conclude that there - Select your answer -is or is not(Item 8) a relationship between the score on comfort and the overall score at the 0.01 level of significance when controlling for - Select your answer -comfort and amenities or comfort and in-house dining or amenities and in-house dining(Item 9 )
