Are Americans whopersonally know someone who is Jewishmore informed about the Holocaust?

The Pew Research Center conducted a survey of 4 questions to determineWhat Americans Know about the Holocaust.Pew also looks at how different the scores are by religious and political party affiliation, educational levels, age, etc.

Visiting Pew's site, one can discover that those identifying themselves asknowing someone who is Jewish is answered an average of 2.6 questions correctly versus 1.5 for those who do not.

To truly decide if the mean difference in correct responses for those who know someone who is Jewish and those who don't is statistically significant, what inference procedure would we perform?

Select one:

a.Hypothesis Test for Difference in Two Sample Proportions

b.None of the other choices are correct

c.Hypothesis Test for a Mean

d.No inference is required; it is obvious that 2.6 is greater than 1.5.

e.Confidence Interval for Means - Matched Pairs

Which of the hypotheses are most appropriateto answer the question, "are Americanswhopersonally know someone who is Jewishmore informed"?

a.H0:know=( \mu \)don't

H1:( \mu \)know>( \mu \)don't

b.H0: pknow=pdon't

Ha: pknow

c.H0: pknow=pdon't

Ha: pknow>pdon't

d.No other choice is correct

e.H0:know=( \mu \)don't

H1:( \mu \)know<( \mu \)don't

and what other statistic(s) would we need in order to actually complete such a test using our calculators?
