I am setting a new standard assessment and want the pass rate in the population to be90%. As a trial, I select 150 participants and ask them to complete the standardassessment. I achieve 129 passes and 21 fails.·Null Hypothesis: Population Pass Rate equals 0.9●Alternative Hypothesis: Population Pass Rate not equal to 0.9*Are the assumptions satisfied for me to proceed with the test?Yes, I have at least 10 passes and 10 failsO Yes, but I must use t instead of Z as the sample size is not very largeYes, the sample size of 150 exceeds 30 so the central limit theorem will holdNe

Molly works for a meat producer, and she needs to determine whether containers of ground beef have the correct fat content. She obtains a random sample of 120 containers of ground beef and finds that 84 percent have the correct fat content. Molly then conducts a hypothesis test of H0:p=0.80H0:p=0.80 versus Ha:p≠0.80Ha:p≠0.80 and calculates a test statistic of 1.10 with a pp-value of 0.273. Which of the following best represents the meaning of the pp-value? If the population proportion is 0.84, the probability of observing a sample proportion of 0.80 is 0.273. A If the population proportion is 0.84, the probability of observing a sample proportion of at least 0.04 less than 0.84 is 0.273. B If the population proportion is 0.80, the probability of observing a sample proportion within 0.04 of 0.80 is 0.273. C If the population proportion is 0.80, the probability of observing a sample proportion at least 0.04 greater than 0.80 is 0.273. D If the…

Explain what the owner should do and how you should proceed given the result of recent hypothesis tests.
Suppose the national average dollar amount for an automobile insurance claim is $777.86. You work for an agency in Michigan and you are interested in whether or not the state average is less than the national average. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≥ 777.86, Alternative Hypothesis: μ < 777.86. You take a random sample of claims and calculate a p-value of 0.0232 based on the data, what is the appropriate conclusion? Conclude at the 5% level of significance. Question 9 options: 1) The true average claim amount is significantly different from $777.86. 2) The true average claim amount is significantly less than $777.86. 3) The true average claim amount is significantly higher than $777.86. 4) We did not find enough evidence to say the true average claim amount is less than $777.86. 5) The true average claim…

An researcher has decided to use significant level α = 0.01 for her experiment. What is the consequence? Group of answer choices The probability of a Type II error is small. There is a small chance of rejecting the null hypothesis when it is true. The probability of a Type I error is large. If the null hypothesis is false, the experimenter will easily be able to reject it.
Suppose that your 95% confidence interval for p is (0.68, 0.74). Based on the confidence interval what would your decision be for the hypothesis test H0: p=0.8 versus H1:p≠0.8 at the α=0.05 level?
