Gun ownership. A friend claims that 39% or less Americans have a gun in their household. To test this claim, I survey 200 random Americans and find that 60 of them have a gun in their household. What should I conclude about my friend's claim? (a) Select the correct null and alternative hypotheses.

• H_o: p = 0.39 H_a: p < 0.39
• H_o: p = 0.3 H_a: p > 0.3
• H_o: p = 0.39 H_a: p > 0.39
• H_o: p = 0.3 H_a: p 0.3
• H_o: p = 0.3 H_a: p < 0.3
• H_o: p = 0.39 H_a: p 0.39

(b) Find the p-value (round to three significant figures). (c) Write the final conclusion using everyday language using a 5% level of significance.

• There is sufficient evidence to support my friend's claim.
• There is not sufficient evidence to reject my friend's claim.
• There is not sufficient evidence to support my friend's claim.
• There is sufficient evidence to reject my friend's claim.
