*Give the value of the correlation coefficient and interpret its meaning. Compute the least-squares regression line for predicting calories (y) from protein (x). Interpret the value of the slope. Predict the number of calories in a fast-food product containing 18 grams of protein. Round to the nearest whole number. What is the 95% confidence interval for the slope. Construct a 99% confidence interval for the slope. Test ? : ? = 0 versus ? : ? ≠ 0. Can you conclude that the amount of protein is useful in predicting the 01 11 number of calories? Use the ? = 0.05 level of significance. Is this a left-tailed test, a right-tailed test, or a two-tailed test? What is the value of the test statistic? Identify the p-value for this procedure. Do not round. Using the p-value method, should ?0 be rejected at the ? = 0.05 level of significance? Why or why not? Can we conclude that the amount of protein in fast-food products is useful in predicting the number of calories?

/transcript Call centers typically have high turnover. The director of human resources for a large bank has compiled data on about 70 former employees at one of the bank's call centers. The accompanying table shows this data. In writing an article about call center working conditions, a reporter has claimed that the average tenure is no more than two years. Formulate and test a hypothesis using these data to determine if this claim can be disputed. Use a level of significance of 0.05. Click the icon to view the call center data. Is there sufficient evidence at the 0.05 level of significance that the average tenure is no more than two years? Determine the null hypothesis, Ho, and the alternative hypothesis, H₁. Ho ...

Anagha is interested in buying a new Model X car and wants to gather information about how the selling price of the car is related to the year of the model. She randomly selects 24 used Model X cars for sale. For each used car, she records the car’s selling price (in dollars) and age (in years). She computes a 96 percent confidence interval to estimate the slope of the regression line relating the age of a used Model X car to its selling price. The resulting confidence interval is given by (−5,556,−3,157). Assume that the conditions for inference on the slope of the regression equation are met. Which of the following is the correct interpretation of the confidence interval? We are 96 percent confident that a Model X car will have a predicted decrease in selling price of between $3,157 and $5,556. A Ninety-six percent of the time, a one-year increase in the age of a Model X car will result in a predicted decrease in selling price of between $3,157 and $5,556. B…

A sample of 100 bears was treated like it was the whole population of Jellystone Park bears, and the mean weight was found to be 800 pounds with standard deviation 12 pounds, the mean blood pressure was 150 with standard deviation 6, and the sample correlation coefficient of weight with blood pressure was found to be .4. Based on this information, what is the regression slope for the SLR equation for predicting blood pressure using observed weight for Jellystone bears?
A tire manufacturer has a 60,000 mile warranty for tread life. The company wants to make sure the average tire lasts longer than 60,000 miles. The manufacturer tests 250 tires and finds the mean life for these tires to be 64,500 miles. What is the alternative hypothesis being tested in this example? The proportion of tires that are worn out after 60,000 miles is greater than 1/2. The mean tire life is equal to 64,500 miles. The mean tire life is less than 60,000 miles. The mean tire life is greater than 60,000 miles.
