Question

Attempts: Keep the Highest: /10 3. Notation for comparing two population means Aa Aa In a study, professor Michael LaCour-Little selected independent random samples of mortgages that were refinanced and mortgages that were not refinanced. (Source: Michael LaCour-Little, "Another Look at the Role of Borrower Characteristics in Predicting Mortgage Prepayments," Journal of Housing Research, Volume 10, Issue 1.) Of the 115 refinanced mortgages, the mean mortgage rate was 8.62 with a sample standard deviation of 0.55. Of the 130 mortgages that were not refinanced, the mean mortgage rate was 8.09 with a sample standard deviation of 0.66. (Note: The sample means match those from the study, but the sample sizes have been reduced.) Suppose you intend to conduct a hypothesis test on the difference in population means. In preparation, you call the sample of mortgages that were refinanced sample 1 and the sample of mortgages that were not refinanced sample 2 Organize the provided data by completing the following table Sample 1 Sample 2 n2 01

Here are the choices for all the blanks

Sample 1

n1= 115 0.55 130 or not provided/unknown

u1= 0.55 8.62 8.09 or not provided/unknown

θ1= 0.55 8.62 not provided/unknown 0.66

s1= not provided/unknown 8.62 0.55 0.66

Sample 2

n2= 115 8.09 130 or not provided/unknown

u2= not provided/unknown 0.66 8.09 or 130
