The recent national elections apparently drew more interest and debate among voters than prior elections. A national sample of 1159 adults, aged 18 and older , surveyed over the telephone (using both landlines and cell phones) revealed that 67% reported that they had given "quite a lot of" thought to the upcoming election. Is there any evidence that the percentage has changed from the reported benchmark of 65% during the same time-frame before the previous selection?

What is the null hypothesis?

A. H0: p < 0.65

B. H0: p > 0.65

C. H0: p =/ 0.65

C. H0: p = 0.65

Calculate the value of the test statistics:

Z=

What is the alternative hypothesis:

A. HA: p < 0.65

B. HA: p > 0.65

C. HA: p =/ 0.65

D. HA: p = 0.65

Find the critical value

Z=

Compare the z-score to the critical value

A. The z-score is equal to the critical value

B. The z-score is greater than the critical value

C. The z-score is less than the critical value

Explain the conclusion

_________ the null hypothesis. There is _________ evidence to conclude that the percentage of adults giving "quite a lot of" thought to the upcoming election is different than it was before the previous election
