A news article that you read stated that 53% of voters prefer the Democratic candidate. You think that the actual percent is smaller. 119 of the 270 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.10 level of significance?

A) Z OR T TEST ??

B) NULL AND ALTERNATIVE HYPOTHESIS IS ??

C) TEST STATISTIC T OR Z =________ (3 DECIMAL PLACES)

D)P-VALUE (4 DECIMAL PLACES )

E) P- VALUE IS > OR < ( WITH UNDERLINE) a

F) REJECT, ACCEPT, OR FAIL TO REJECT ??

G) A, B , OR C CONCLUSION??

A)The data suggest the populaton proportion is significantly smaller 53% at α= 0.10, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller 53%

B)The data suggest the population proportion is not significantly smaller 53% at α = 0.10, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller 53%.

C)The data suggest the population proportion is not significantly smaller 53% at α= 0.10, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 53%.

H) Interpret the p-value in the context of the study. A B OR C

A) If the sample proportion of voters who prefer the Democratic candidate is 44% and if another 270 voters are surveyed then there would be a 0.16% chance of concluding that fewer than 53% of all voters surveyed prefer the Democratic candidate.

B) There is a 53% chance of a Type I error.

C) If the population proportion of voters who prefer the Democratic candidate is 53% and if another 270 voters are surveyed then there would be a 0.16% chance fewer than 44% of the 270 voters surveyed prefer the Democratic candidate.

I) Interpret the level of significance in the context of the study. A B OR C

A) There is a 10% chance that the earth is flat and we never actually sent a man to the moon.

If the proportion of voters who prefer the Democratic candidate is smaller 53% and if another 270 voters are surveyed then there would be a 10% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is equal to 53%.

B) There is a 10% chance that the proportion of voters who prefer the Democratic candidate is smaller 53%.

C) If the population proportion of voters who prefer the Democratic candidate is 53% and if another 270 voters are surveyed then there would be a 10% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is smaller 53%
