Minnesota had the highest tumout rate of any state for the 2016 presidential election.t Political analysts wonder if turnout in rural Minnesota was higher than turnout in the urban areas of the state. A sample shows that 648 of 864 registered voters from rural Minnesota voted in the 2016 presidential election, while 378 out of 525 registered voters from urban Minnesota voted. (a) Formulate the null and alternative hypotheses that can be used to test whether registered voters in rural Minnesota were more likely than registered voters in urban Minnesota to vote in the 2016 presidential election. (Let P, = the population proportion of voters in rural Minnesota who voted in the 2016 election and p, the population proportion of voters in urban Minnesota who voted in the 2016 election.) o Ho: P1- P2 2 0 Ha P1- P2 0 o Ho: P1- P2 * 0 H3i P1- P2 = 0 Ho: P1- P2 < 0 H P1- P2 = 0 (b) What is the proportion of sampled registered voters in rural Minnesota that voted in the 2016 presidential…
It is believed 7.6% of a population is born with sickle cell anemia traits. If we wish to test this theory and randomly gather a sample of 100 individuals, will we be able to perform a hypothesis test? Group of answer choices Yes, because we have more than 30 individuals Yes, because the sample size is large and random No, because the sample was no random No, because we don't have enough successes/failures
Suppose a researcher comes up with a new drug that treats Borderline Personality Disorder (BPD). She assigns some patients who have BPD to receive a placebo and others to receive the new drug. The null hypothesis is that the drug will have no effect. 1. In this case, what would be the Type I error? In this case, what would be the Type II error?
A college professor states that this year's entering students appear to be smarter than entering students from previous years. The college's records indicate that the mean IQ for entering students from earlier years is 110.4. Suppose that we want to sample a small number of this year's entering students and carry out a hypothesis test to see if the professor's statement can be supported. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test. H0= H1=
We are comparing two samples during a hypothesis test. Sample A has a z-test statistic of 1.58 and sample B has a z-test statistic of -0.34. We can say then that... If H-naught is true, then Sample B has a higher probability of occurring while Sample A has a lower probability of occurring. If H-naught is true, then Sample A has a higher probability of occurring while Sample B has a lower probability of occurring. We reject the null hypothesis. If H-naught is rejected, then Sample A has a higher probability of occurring while Sample B has a lower probability of occurring.

According to a New York Times/CBS News poll conducted during June 24–28, 2011, 55% of the American adults polled said that owning a home is a very important part of the American Dream (The New York Times, June 30, 2011). Suppose this result was true for the population of all American adults in 2011. In a recent poll of 1780 American adults, 60% said that owning a home is a very important part of the American Dream. Perform a hypothesis test to determine whether it is reasonable to conclude that the percentage of all American adults who currently hold this opinion is higher than 55%. Use a 10% significance level, and use both the p-value and the critical-value approaches. Round your answers for the observed value of z and the critical value of z to two decimal places, and the p-value to four decimal places.zobserved =Enter you answer; z_observed p-value =Enter you answer; p-value Critical value =Enter you answer; Critical value
