uutied from my test for not working this problem Question 16 Your answer is CORRECT This is a written question, worth 10 points. DO NOT place the problem proctor will fill this out credit. Problem Code: 1671 code on the answer sheet. A after exam submission. Show all steps (work) on your answer sheet for full Consumer Reports rated 77 cereals on a scale of 0 to 100. The number of grams of sugar contained in each sumer Reports rating as the dependent variable, computer output of the data is as follows (the p-values serving of the corresponding cereals was also recorded. Using sugar as the explanatory variable and the Consu are intentionally left blank): Predictor Coef Constant 59.281.948 30.43 Sugars (- - StDev T 2.41 0.24 10.12 s-9.146 R-Sq-57.7% R-Sq(adj)=57.1% Part a: What is the regression equation? Part b: Calculate the 95% confidence interval of the slope of the regression line for all cereals. Part c: Use the information provided to test whether there is a significant relationship between the sugar content and the Consumer Report rating at the 5% level. a) I have placed my work and my answer on my answer sheet. b) I want to have points deducted from my test for not working this problem. Question 17Explanation / Answer
a)
Consumer Reports Rating=59.28-2.41*Sugars
b)
DF=75, tCRIT is 1.99
-2.41+/-1.99*0.24= -2.8876 to -1.9324
c)
P-value would turn out to be 0.00 and it is less than a. Hence the variable is significant in estimating the variation in the dependent variable.
