Test the claim that the proportion of children from the low-income group that drew the nickel too large is greater than the proportion of the high-income group that drew the nickel too large. Test at the 0.05 significance level.
24 of 40 children in the low-income group drew the nickel too large, and 10 of 35 did in the high-income group.
a) If we use L to denote the low-income group and H to denote the high-income group, identify the correct alternative hypothesis.
- H1:μL≠μHH1:μL≠μH
- H1:pL≠pHH1:pL≠pH
- H1:μL>μHH1:μL>μH
- H1:pL>pHH1:pL>pH
- H1:pL<pHH1:pL<pH
- H1:μL<μHH1:μL<μH
b) The test statistic value is____________(two decimal places):
c) Using the P-value method, the P-value is____________ (4 decimal places):
