regressionsales = B1 + B2price + B3price? + Baadvert + eWe estimate the above regression in R and obtain the following output## Coefficients:##Estimate Std. Error## (Intercept)## price## I(price^2)1.51.50.50.5-0.51.5## advert0.40.2where the row I(price?) refers to the estimates for ß3. Suppose we are interested in testing the null hypothesis that expected sales do not depend on advertising againstthe alternative that expected sales do depend on advertising. What is the p-value for this hypothesis test (use a normal approximation)? In the options below, Z ~ N(0, 1).O a. 1- P(Z < 2)O b. All other options are incorrect.O c. 1- P(Z > 0.4//0.2)O d. 2P(Z > 2)O e. 2P(Z > 0.4//0.2)

From the given information, Null Hypothesis: H0: The expected sales do not depend on advertising.…

A researcher wishes to examine the relationship between years of schooling completed and the number of pregnancies in young women. Her research discovers a linear relationship, and the least squares line is: ˆy=5−3xy^=5-3x where x is the number of years of schooling completed and y is the number of pregnancies. The slope of the regression line can be interpreted in the following way: When amount of schooling increases by one year, the number of pregnancies tends to increase by 5. When amount of schooling increases by one year, the number of pregnancies tends to decrease by 3. When amount of schooling increases by one year, the number of pregnancies tends to increase by 3. When amount of schooling increases by one year, the number of pregnancies tends to decrease by 5.
Data is collected on the relationship between time spent playing video games and time spent with family. The data is shown in the table and the line of best fit for the data is y^=−0.57x+102.67. Assume the line of best fit is significant and there is a strong linear relationship between the variables. Video Games (Minutes) 40557085 Time with Family (Minutes) 80726255 According to the line of best fit, what would be the predicted number of minutes spent with family for someone who spent 46 minutes playing video games? Round the answer to one decimal place. What is the predicted number number of minutes spent with family?
