Question
Multiple Linear RegressionIf the p-value for the overall significance hypothesis test of the multiple linear regression is 0.007, which of the following statements is correct at a 99 percent confidence level?The annual income has a significant influence on the credit card bill.The annual income and annual credit card charges have a significant influence on the credit card bill.The annual income, annual credit card charges, and household size have a significant influence on the credit card bill.At least one of the annual income, annual credit card charges, and household size has a significant influence on the credit card bill.Can’t comment at a 99 percent confidence level.
Solution
The correct statement at a 99 percent confidence level is: "At least one of the annual income, annual credit card charges, and household size has a significant influence on the credit card bill."
Here's the step-by-step reasoning:
-
The p-value of 0.007 is less than the significance level of 0.01 (which corresponds to a 99 percent confidence level). This means that the null hypothesis (which states that none of the predictors have a significant influence on the credit card bill) can be rejected.
-
However, this does not specify which of the predictors (annual income, annual credit card charges, and household size) are significant. It only indicates that at least one of them is significant.
-
Therefore, the only correct statement is that at least one of the predictors has a significant influence on the credit card bill. The other options are too specific and cannot be confirmed with the given information.

A consumer's spending is widely believed to be a function of their income. To estimate this relationship, a university professor randomly selected 19 of his students and collected information on their spending (Y, in dollars) and income (X, in dollars) patterns in week 6 of the semester. Assuming a linear relationship between Y and X, the professor used the least-squares method and found that the Y intercept = 20.90 and the slope = 0.66. The professor also found that the standard error of the slope was 0.08. Based on this information, what conclusion should you reached at the 5% level of significance when testing the null hypothesis that there is no linear relationship between the two variables, X and Y? a. There is sufficient evidence at the 5% level of significance to conclude that there is no significant linear relationship between X and Y. b. There is sufficient evidence at the 5% level of significance to conclude that there is a significant linear relationship between X and Y. c. There is sufficient evidence at the 5% level of significance to conclude that there is a significant linear relationship between the Y intercept and the slope. d. There is insufficient evidence at the 5% level of significance to conclude that there is a significant linear relationship between X and Y.
Confidence in banks: A poll conducted asked a random sample of 1239 adults in the United States how much confidence they had in banks and other financial institutions. A total of 158 adults said that they had a great deal of confidence. An economist claims that greater than 11% of U.S. adults have a great deal of confidence in banks. Can you conclude that the economist's claim is true?
