Suppose that in the exit poll from the state of Florida during the year 2000 presidential elections in the United States, the pollsters recorded only the votes of the two candidates who had any chance of winning, Democrat Albert Gore and Republican George W. Bush. The polls close at 8:00 PM. The number of votes cast for the Republican in the poll is x=407. The sample size is n=765. Can the television networks conclude from these data that the Republican candidate will win the state? Set up the null and alternative hypothesis, the rejection region and the conclusion of the test to answer this question. Use a 1% significance level Select one: O a. Yes. The television networks CAN conclude from these data that the Republican candidate will win the state. The sample proportion is 1.77 standard errors from the null value of 0.5. The rejection region is any sample proportion at or below 2.33 standard errors from the null value of 0.5. O b. Yes. The television networks CAN conclude from these data that the Republican candidate will win the state. The sample proportion is 2.33 standard errors from the null value of 0.5. The rejection region is any sample proportion at or above 1.77 standard errors from the null value of 0.5. O c. NO. The television networks CAN'T conclude from these data that the Republican candidate will win the state. The sample proportion is 1.77 standard errors from the null value of 0.5. The rejection region is any sample proportion at or above 2.33 standard errors from the null value of 0.5.

Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

The number of votes cast for the Republican in the poll is x=407. The sample size is n=765.
Can the television networks conclude from these data that the Republican candidate will win the state? Set up the null and alternative hypothesis, the rejection region and the
conclusion of the test to answer this question. Use a 1% significance level
Select one:
O a. Yes. The television networks CAN conclude from these data that the Republican candidate will win the state. The sample proportion is 1.77 standard errors from the null value
of 0.5. The rejection region is any sample proportion at or below 2.33 standard errors from the null value of 0.5.
O b. Yes. The television networks CAN conclude from these data that the Republican candidate will win the state. The sample proportion is 2.33 standard errors from the null value
of 0.5. The rejection region is any sample proportion at or above 1.77 standard errors from the null value of 0.5.
O c. NO. The television networks CAN'T conclude from these data that the Republican candidate will win the state. The sample proportion is 1.77 standard errors from the null value
of 0.5. The rejection region is any sample proportion at or above 2.33 standard errors from the null value of 0.5.
O d. Yes. The television networks CAN conclude from these data that the Republican candidate will win the state. The sample proportion is significantly higher than the null value
0.5.
O e. T
Transcribed Image Text:A statistics instructor believes that fewer than 20% of Silk Valley College (SVC) students attended the opening night midnight showing of the latest Star Wars movie. She surveys 84 of
her students and finds that 11 of them attended the midnight showing. At a 1% level of significance, an appropriate conclusion is:
Select one:
O a. There is insufficient evidence to conclude that the percent of SVC students who attended the midnight showing of Star Wars is less than 20%
O b. There is sufficient evidence to conclude that the percent of SVC students who attended the midnight showing of Star Wars is more than 20%
O c. There is sufficient evidence to conclude that the percent of SVC students who attended the midnight showing of Star Wars is less than 20%
O d. There is insufficient evidence to conclude that the percent of SVC students who attended the midnight showing of Star Wars is at least 20%
e. None of the above
