A sample of 103 mortgages approved during the current year showed that 39 were issued to a single-earner family or individual. The historical percentage is 31 percent. At the .05 level of significance in a right-tailed test, has the percentage of single-earner or individual mortgages risen? (a-1) Hg: n s.31 versus H1: 1 > .31. Choose the right option. a. Reject Hg if zcalc > 1.645 b. Reject Ho if zcalc < 1.645 a b (a-2) Calculate the test statistic. (Round intermediate calculations to 2 decimal places. Round your answer to 4 decimal places.)
