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 0.01 significance level.
25 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.
Нi: PL <PH
Ні: PL > PH
Ні: PL > PH
Hl > Ir1:'H
H1:PL + PH
b) The test statistic value is (two decimal places):
c) Using the P-value method, the P-value is (4 decimal places):
d) Based on this, we
Reject Ho
Fail to reject Ho
e) Which means
There is not sufficient evidence from the sample data to warrant rejection of the claim
OThere is not sufficient evidence from the sample data to support the claim
OThe sample data supports the claim
There is sufficient evidence from the sample data to warrant rejection of the claim
