A philanthropic organization sent free mailing labels and greeting cards to a random sample of 100,000 potential donors on their mailing list and received 5196 donations. They have had acontribution rate of 5% in past campaigns, but a staff member hopes that the rate will be higher if they run this campaign as currently designed. Complete parts a through c below. Assumethe independence assumption is met.a) What are the hypotheses?Which hypotheses below will test the staff member's hopes?OA. Ho: p*0.05HA: P=0.05Ọ C. Ho:p=0.05B. Ho:p>0.05HA: P=0.05HA: P 0.05OD. Ho: p<0.05HA: P = 0.05E. Ho: p=0.05HA: P >0.05OF Hoip=0.05HA: P<0.05b) Are the assumptions and conditions for inference met?Which assumptions and conditions below are met? Select all that apply.A. The success/failure condition is met.B. The 10% condition is met.C. The randomization condition is met.D. The independence assumption is met.c) Do you think the donation rate would rise?OA. The P-value is too high to conclude that the rate would be above the previous campaign contribution rate of 5%.B. The P-value is high enough to conclude that the rate would be above the previous campaign contribution rate of 5%.C. The P-value is low enough to conclude that the rate would be above the previous campaign contribution rate of 5%.D. The P-value is too low to conclude that the rate would be above the previous campaign contribution rate of 5%.E. Inference is not possible since the assumptions and conditions are not met.

Country Magazine reports that celebrity MySpace accounts have an average of 4 million friends. Celebologist Chuck Norris thinks that it's actually different than that. Norris randomly samples 43 celebrities on MySpace and finds an average of 3 million friends. Which is the best set of hypotheses to test Chuck Norris's claim?
Exit polling is a popular technique used to determine the outcome of an election prior to results being tallied. Suppose a referendum to increase funding for education is on the ballot in a large town (voting population over 100,000). An exit poll of 500 voters finds that 245 voted for the referendum. How likely are the results of your sample if the population proportion of voters in the town in favor of the referendum is 0.51? Based on your result, comment on the dangers of using exit polling to call elections. Question content area bottom Part 1 How likely are the results of your sample if the population proportion of voters in the town in favor of the referendum is 0.51?
Among students at a nearby college, the proportion who say they’re interested in their congressional district’s election results has traditionally been 70%. After a series of lackluster debates on campus, a political scientist claims that the proportion, p, of students at the college who say they’re interested in their districts election results is now less than 70%. A pill is commissioned, and 154 out of random sample of 230 students at the college say they’re interested in their districts election results. Is there enough evidence to support the political scientist’s claim at the 0.05 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table.
A study considered the question, “Are you a registered voter?” Accuracy of response was confirmed by a check of city voting records. Two methods of survey were used: a face-to-face interview and a telephone interview. A random sample of 93 people were asked the voter registration question face-to-face. Seventy-nine respondents gave accurate answers. Another random sample of 83 people was asked the same question during a telephone interview. Seventy-four respondents gave accurate answers. Assume that the samples are representative of the general population. Test the claim that there is a difference in the proportion of accurate responses from face-to-face compared with telephone interviews. Use alpha=.05 What is the null hypothesis? What is the alternative hypothesis? What distribution are you using? What test are you running? What is your conclusion?
Exit polling is a popular technique used to determine the outcome of an election prior to results being tallied. Suppose a referendum to increase funding for education is on the ballot in a large town (voting population over 100,000). An exit poll of 500 voters finds that 260 voted for the referendum. How likely are the results of your sample if the population proportion of voters in the town in favor of the referendum is 0.49? Based on your result, comment on the dangers of using exit polling to call elections. How likely are the results of your sample if the population proportion of voters in the town in favor of the referendum is 0.49? The probability that more than 260 people voted for the referendum is (Round to four decimal places as needed.)

A telecommunications company provided its cable tv subscribers with free access to a new channel for a month. It then chose a sample of 700 viewers and asked them whether they would be willing to pay an extra $10 per month to continue access to the channel. Total of 33 replied that they would be willing to pay. The marketing director of the company claims that more than 5% of all its subscribers would be willing to pay. Can you conclude that the directors claim is true? Use 0.01 level of significance.

In recent years, many states have enacted tougher voter identification laws requiring a government issued photo ID. Proponents claim that these laws are necessary to reduce voter fraud. Opponents claim that voter fraud is rare and that since as many as 11% of eligible voters do not have the required identification, these tougher laws will discourage millions of minorities and low-income Americans from voting. The Washington Post conducted a national poll (July 7-19, 2012) and found that 1558 out of 2064 adults supported the tougher voter ID laws. 1)Construct a 95% confidence interval for the proportion of adults who approve of tougher voter ID laws. Document your work in the space provided below. Document how you computed the margin of error and the confidence interval in the space provided below. Round all numbers to 4 decimal places. 2)Is it likely that three-fourths of adults approve of these new laws?
None
