*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?

Based on the scatter plot above, describe the relationship between the amount of cost damage and the distance from nearest fire station to the residential. Determine the regression line for the above regression output. Interpret the slope coefficient of distance to the nearest station affecting the amount of fire cost damage. Compute the correlation coefficient and interpret its meaning. Does the distance to the nearest fire station has significant influence on the cost damage amount? Conduct a test at 1% significance level. ] Predict the fire cost damage generated if the distance from nearest fire station is 2.5 kilometers. Is this estimate reliable? Explain. []
/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 ...

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.
