Suppose a consumer group suspects that the proportion of households that have threeor more cell phones is 39%. A cell phone company has reason to believe that the proportion isnot 39%. Before they start a big advertising campaign, they conduct a hypothesis test. Theirmarketing people survey 186 households with the result that 93 of the households have three ormore cell phones. Conduct a hypothesis test to test the cell phone company’s belief at the 5%significance level. show all steps
11) Fill your answer in the Blank. Assume that you plan to use a significance level of α = 0.05 to test the claim that p1 = p2, Use the given sample sizes and numbers of successes to find the P-value for the hypothesis test.n1 = 60, n2 = 75, x1 = 20, x2 = 35
A national survey conducted in 2011 among a simplerandom sample of 1507 adults shows that 56% of Americans think the Civil War is still relevant toAmerican politics and political life. a) Conduct a hypothesis test to determine if these data provide strong evidence that the majority (> 50%)of the Americans think the Civil War is still relevant. Please calculate the test statistic, the P-value,and make a conclusion at a 1% significance level. b) Which of the following is the correct interpretation of the p-value calculated in part (a)?i. It’s the probability that the majority (> 50%) of Americans think the Civil War is still relevantto American politics and political life, given that 56% of the sample of size 1507 think so.ii. It’s the probability that that 50% of Americans think the Civil War is still relevant to Americanpolitics and political life, given that 56% of the sample of size 1507 think so.iii. It’s the probability to obtain a sample of size 1507 that 56% or more think…
In a recent study, researchers found that 40 out of 250 boys aged 7-13 were overweight or obese. On the basis of this study can we conclude that more than 15% of the boys aged 7-13 in the sampled population are overweight or obese? Use a 5% level of significance. 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic, and 5) your conclusion including a comparison to alpha or the critical value.
A university has decided to introduce the use of plus and minus grading as long as there is evidence that 60% of the faculty is in support of this change. Write an appropriate null hypothesis and alternate hypothesis to test if the proportion is greater than 60%.
A sample of 1200 adults revealed that 115 of them are left-handed. Test the claim with a significance level of 0.05 that 15% of all adults are left-handed. a) identify the claim, the null hypothesis, and the alternative hypothesis? b) Which type of test will be used? c) What critical values are there? d) What is the value of the test statistic? e) What is the decision? f) What is the conclusion?
Minnesota had the highest turnout rate of any state for the 2016 presidential election.† Political analysts wonder if turnout in rural Minnesota was higher than turnout in the urban areas of the state. A sample shows that 627 of 836 registered voters from rural Minnesota voted in the 2016 presidential election, while 414 out of 575 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 p1 = the population proportion of voters in rural Minnesota who voted in the 2016 election and p2 = the population proportion of voters in urban Minnesota who voted in the 2016 election.) (b) What is the proportion of sampled registered voters in rural Minnesota that voted in the 2016 presidential election? (c) What is the proportion of sampled registered voters in urban…
PLEASE ONLY SELECT THE ANSWERS AS SHOWN FOR THE MULTIPLE CHOICE, SUCH AS OPTION 1, 2, ETC. 1) A genetic experiment involving peas yielded one sample of offspring consisting of 427 green peas and 127 yellow peas. Use a 0.01 significance level to test the claim that under the same circumstances, 25% of offspring peas will be yellow. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution. What are the null and alternative hypotheses? A. H0: p=0.25 H1: p<0.25 B. H0: p=0.25 H1: p>0.25 C. H0: p≠0.25 H1: p=0.25 D. H0: p=0.25 H1: p≠0.25 E. H0: p≠0.25 H1: p<0.25 F. H0: p≠0.25 H1: p>0.25 2) What is the test statistic? Z= (Round to two decimal places as needed.) 3) What is the P-value? P-value= (Round to four decimal places as needed.) 4) What is the…
Country clerk in Essex County New Jersey selected candidates for positions on election ballot. Democrats were selected first in 40 of 41 ballots. Because he was supposed to use a method of random selection Republicans claimed that instead of using randomness he used a method that favor Democrats use a 0.01 significance level to test the claim that the ballot selection method favors Democrats.
