QUESTION 1 In a hypothesis test, if we reject the null hypothesis at the significance level of 59%, then we definitely reject this null hypothesis at the significance level of 1%. O True O False QUESTION 2 In a simple regression analysis residual plot, if the spread of residuals is obviously increasing in the dependent variable, there is a "Heteroskedasticity" problem. O True O False QUESTION 3 In multiple regression, it is always the case that the larger the RZ is, the better the model is. O True O False QUESTION 4 [Red Cross Red Shield] The distribution of the amount paid in health claims by Red Cross Red Shield (RCRS), a medical insurance company, on individual health insurance plans for college students has mean $800, median $700, and standard deviation $500. Based on this information alone, can you determine the exact probability that the annual amount paid in claims to a single randomly chosen participant is greater than $500? 3. Since we do not know the exact distribution, we cannot determine the probability that the annual amount paid in claims to a single randomly chosen participant is greater than $500 with mean and standard deviation alone. O b. P(More than $500) = 0.275 O C. P(More than $500) = 0.425 O d. P(More than $500) = 0.5
