A study was conducted using a random sample of Taco Bell products to determine whether grams of protein content (x) was related to calorie content (y). The following information was obtained: ŷ = 402.3 – 0.508x, Coefficient of determination (r2) = 53.14% a. What is the value of the correlation between protein content and calorie content (r)? b. If the product had 50 grams of protein, what is the calorie content?
Tourism is extremely important to the economy of Florida. Hotel occupancy is an often-reported measure of visitor volume and visitor activity (Orlando Sentinel, May 19, 2018). Hotel occupancy data for February in two consecutive years are as follows. Ho: P1 P2 less than or equal to 0 Ha P1 P2 greater than 0 b. What is the estimated proportion of hotel rooms occupied each year (to 2 decimals)? 1,435 1,750 1,422 1,800 a. Formulate the hypothesis test that can be used to determine whether there has been an increase in the proportion of rooms occupied over the one-year period. Let P1 = population proportion of rooms occupied for current year P2 = population proportion of rooms occupied for previous year Current year Previous Year .82 .05 p-value = .7997 Using a 0.05 level of significance, what is your conclusion? .014 c.

Because colas tend to replace healthier beverages and colas contain caffeine and phosphoric acid, researchers wanted to know whether cola consumption is associated with lower bone mineral density in women. The accompanying data lists the typical number of cans of cola consumed in a week and the femoral neck bone mineral density for a sample of 15 women. Complete parts (a) through (f) below.

Researchers examined the influence of a television program on children's aggressiveness. The number of aggressive responses was measured during an observation period after viewing the television program. Imagine that the known national average for number of aggressive responses typically performed by children who do not watch television is 6.847. Use the data below to conduct an analysis to determine if the number of aggressive responses on average is different from the national average. The data for this study can be found in the datafile: nresponses.csv. What is the null and alternative hypotheses in words and symbols? Is the assumption(s) met? Please explain your answer and proceed with the analysis even if the assumption(s) is not met. What do you conclude from your analysis? Based on your response in “c” above, identify and explain the type of error you could be making.
A magazine used the summated rating of 10 restaurants to predict the cost of a restaurant meal. For that data, SSR = 131,150.78 and SST = 144,854.59. Complete parts (a) through (c). ..... a. Determine the coefficient of determination, r2, and interpret its meaning. r2 = (Round to four decimal places as needed.) Interpret the meaning of r2. It means that % of the variation in the cost of a meal v be explained by the variation in summated ratings. (Round to two decimal places as needed.) b. Determine the standard error of the estimate. Syx = (Round to four decimal places as needed.) %3D can c. How useful do you think this regression model is for pi fa meal? cannot A. It is not very useful for predicting the cost of a meal because the coefficient of determination is close to 0 and the standard error of the estimate is fairly large. B.
