Your local school board wants to determine the proportion of people who plan on voting for the school levy in the upcoming election. They conduct a random phone poll, where they contact 150 individuals and ask them whether or not they plan on voting for the levy. Of these 150 respondents, 78 people say they plan on voting for the levy. The school board wants to determine whether or not the data supports the idea that more than 50% of people plan on voting for the levy. Calculate the p-value for the one-sided Hypothesis test described in this example. (Hint: Find the test statistic and then use the tables to find the p-value.) 0.20 < p-value < 0.30 0.6879 0.3121 greater than 0.5 0.4899

The NORC found that approximately 67% of people in the U.S. favor capital punishment. How large a sample is necessary to be 99% sure that the point estimate will be within a distance of .01 from p?
A conservative radio talk show host with a large audience is interested in the proportion p ofadults in his listening area who think the drinking age should be lowered to eighteen. To findthis out, he poses the following question to his listeners: “Do you think that the drinking ageshould be reduced to eighteen in light of the fact that eighteen year‐olds are eligible for militaryservice?” He asks listeners to phone in and vote “Yes” if they agree the drinking age should belowered and “No” if not. Of the 100 people who phoned in, 70 answered “Yes.” a. List one source of sampling bias (i.e. bias based on the people included in the sample). b. List another source of bias (sampling or non-sampling).
You plan to survey fans regarding whether they pay $1 more for an upcoming album if it came with a code that lets them download cool images and videos from the bands website. If you want the margin of error to be no more than 4.25% what is the minimum number of people you need to survey? Suppose you do this survey using the number calculated in part (a) and 90% of people surveyed said they'd pay that extra dollar. Your boss is concerned that your sample was too limited geographically, so you do the survey all over again ( sampling a new, equal size, group of people). The second time you do the survey, 70% of people surveyed say they'd pay that extra dollar. Which one of the following statements are true? A. The second time you did the survey, the margin of error was smaller. B. The second time you did the survey, the margin of error was equal. C The second time you did the survey the margin of error was larger
In a Gallup poll of 1236 adult respondents, 6% said that bad luck follows breaking a mirror. That percentage has a margin of error of 1.5 percentage points. Why is it misleading to state that the percentage is 6% with a margin of error of 1.5%?
The brand manager for a brand of toothpaste must plan a campaign to increase brand recognition. He wants to first determine the percentage of adults who have heard of the brand.

(Assume that nothing is known about the percentage of adults who have heard of the brand.)

A tv report conducted a survey of 681 people in Washington state and found that 26% of the population believe that Mt Saint Helen's will have a repeat eruption this year.

Español Among college students, the proportion p who say they're interested in their congressional district's election results has traditionally been 65%. After a series of debates on campuses, a political scientist daims that the proportion of college students who say they're interested in their district's election results is more than 65%. A poll is commissioned, and 173 out of a random sample of 260 college students say they're interested in their district's 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. (If necessary, consult a list of formulas.) (a) State the null hypothesis H, and the alternative hypothesis H1. H, :0 H :0 (b) Determine the type of test statistic to use. (Choose one) D=0 OSO (c) Find the value of the test statistic. (Round to three or more decimal places.) ロ=ロ O
