A ski resort asked a random sample of guests to rate their satisfaction on various attributes of their visit on a scale of 1–5 with 1 = very unsatisfied and 5 = very satisfied. The estimated regression model was Y = overall satisfaction score, X₁ = lift line wait, X₂ = amount of ski trail grooming, X₃ = safety patrol visibility, and X₄ = friendliness of guest services.

Predictor	Coefficient
Intercept	2.9833
LiftWait	0.1458
AmountGroomed	0.2562
SkiPatrolVisibility	0.0428
FriendlinessHosts	−0.1298

(a) Write the fitted regression equation. (Round your answers to 4 decimal places. Negative values should be indicated by a minus sign.)

yˆy^ = ______ + ______ * LiftWait + ________ * AmountGroomed +________ * SkiPatrolVisibility +________ * FriendlinessHosts

(b) Interpret each coefficient.

Overall satisfaction "increases" remains same with an increase in satisfaction for each individual predictor except for friendliness of hosts.

(c) Would the intercept seem to have meaning in this regression?

Yes
No XXXXX

(d) Make a prediction for Overall Satisfaction when a guest’s satisfaction in all four areas is rated a 3. (Round your answer to 4 decimal places.)

Overall satisfaction score ____________

Expert Solution

Note that the estimated overall satisfaction score is 3.9439 on an average when all scores are equal to 3.

A random sample of 172 students was asked to rate on a scale to from 1 (not important) to 5 (extremely important) health benefits as a job characteristic (note that the rating scale can also have decimals, i.e. a student can give a rating of 1.32). The sample mean rating was 3.31, and the sample standard deviation was 0.70. For a type I error of 1% (alpha), can you be reasonably certain that the average rating is more than 3...

A recent study of a random sample of employees evaluated whether satisfaction is related to job performance. 250 employees who have been employed greater than 10 years, and 250 employees who have been employed less than 10 years were included in the study. The number of employees who still worked for the company after this study were 236 and 226, respectively. Assume that the two groups are independent, and that satisfaction rates follow a normal distribution in the population. Use...

A random sample of 774 subjects was asked to identify the day of the week that is best for quality family time. Consider the claim that the days of the week are selected with a uniform distribution so that all days have the same chance of being selected. The table below shows goodness-of-fit test results from the claim and data from the study. Test that claim using either the critical value method or the P-value method with an assumed significance...
