A credit union advertises that recipients of their home equity loans have an average credit score of only 620. A skeptical consumer claims that the average credit score of home equity loan holders from this particular credit union is higher than that. She wishes to test this claim at the  α=0.10α=0.10 level of significance. (Round your results to three decimal places) Which would be correct hypotheses for this test?

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
