The test claim that the proportion of children from the low income group that drew the nickle too large is greater than the proportion of the high income group that drew the nickle too large. Test at the 0.05 significance level.

25 of 40 children in the low income group drew the nickle too large, and 7 of 35 in the high income group.

A) if we us L to denote the low income group and H to denote the high income group, identify the correct alternative hypothesis

H1:UL>UH

H1:UL<UH

H1:PL(cannot equal)PH

H1:UL(cannot equal)UH

H1:PL<PH

H1:PL>PH

The test statistic for this sample? (Report answer TWO decimal places.)

test statistic =

USING THE P-VALUE METHOD, What is the p-value is? (Report answer to four decimal places.)

p-value =


Based on this, we...

  • reject Ho

  • OR

  • fail to reject Ho


Which means...

  • There is sufficient evidence from the sample data to warrant rejection of the claim.

  • There is not sufficient evidence from the sample to warrant rejection of the claim.
