The proportion of residents in a community who recycle has traditionally been 69%. A policy maker claims that the proportion is less than 69% now that one of the recycling centers has been relocated, and the policy maker wishses to carry out a hypothesis test. State the null hypothesis H0 and the alternative hypothesis H1 that the policy maker would use for this test. H0: H1:

Is this correct?

A recent drug survey showed an increase in the use of drugs and alcohol among local high school seniors as compared to the national percentage. Suppose that a survey of 100 local seniors and 100 national seniors is conducted to see if the proportion of drug and alcohol use is higher locally than nationally. Locally, 65 seniors reported using drugs or alcohol within the past month, while 60 national seniors reported using them. Conduct a hypothesis test at the 5% level.NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) Part (a) State the null hypothesis. H0: plocal ≠ pnational H0: plocal > pnational      H0: plocal = pnational H0: plocal < pnational Part (b) State the alternative hypothesis. Ha: plocal < pnational Ha: plocal = pnational      Ha: plocal ≠ pnational Ha: plocal > pnational…

A person wonders if eating breakfast before working out would decrease their 100-meter run times or not. The person records 8 times after eating breakfast (WB) and 8 times without breakfast (WOB). Examine if having breakfast before running does in fact lower 100-meter times. That is, test the null hypothesis: uWOB=uWB vs. Alternative: uWOB >uWB. Find the P-value.

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…

A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 097%. Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis H and the alternative hypathesis A that we would use for this test. H 0 H:0 ?

In a sample of 183 male job-holders, 55% said that they are satisfied with their jobs. In another sample of 171 female job-holders, 65% said that they are satisfied with their jobs. The null hypothesis is that the proportions of all female and all male job-holders who are satisfied with their jobs are equal. The alternative hypothesis is that the proportion of all female job-holders who are satisfied with their jobs is greater than the proportion of all male job-holders who are satisfied with their jobs. The significance level is 2%. What is the approximate p-value for this test? e. 0.9732 b. 0.9975 d. 1.0000 a. 0.9139 c. 0.9724

The proportion of residents in a community who recycle has traditionally been  70% . A policy maker claims that the proportion is less than  70%  now that one of the recycling centers has been relocated, and the policy maker wishses to carry out a hypothesis test. State the null hypothesis  H0  and the alternative hypothesis  H1  that the policy maker would use for this test. H0 :    H1 :

The National Association of Realtors reported that 26% of home buyers in the state of Florida are foreigners in 2012. The correct hypothesis statement to test the validity of this report would be a. O b. O c. d. H0: p = 0.26; H1: p + 0.26. H0: p = 0.26; H1: p > 0.26. H0: p = 0.26; H1: p < 0.26. H0: p = 0.26; Hl: p = 0.26.

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=
