Gun ownership. A friend claims that 33% or less Americans have a gun in their household. To test this claim, I survey 200 random Americans and find that 64 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. Ho: p = 0.33 Ha: p > 0.33 Ho: p = 0.33 Ha: p < 0.33 Ho: p = 0.33 Ha: p ≠ 0.33 Ho: p = 0.32 Ha: p > 0.32 Ho: p = 0.32 Ha: p ≠ 0.32 Ho: p = 0.32 Ha: p < 0.32 (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 not sufficient evidence to reject my friend's claim. There is sufficient evidence to reject my friend's claim. There is sufficient evidence to support my friend's claim. There is not sufficient evidence to support my friend's claim.

Gun ownership. A friend claims that 33% or less Americans have a gun in their household. To test this claim, I survey 200 random Americans and find that 64 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.
- Ho: p = 0.33
Ha: p > 0.33 - Ho: p = 0.33
Ha: p < 0.33 - Ho: p = 0.33
Ha: p ≠ 0.33 - Ho: p = 0.32
Ha: p > 0.32 - Ho: p = 0.32
Ha: p ≠ 0.32 - Ho: p = 0.32
Ha: p < 0.32
(b) Find the p-value (round to three significant figures).
(c) Write the final conclusion using everyday language using a 5% level of significance.
