You are conducting a study to see if the proportion of men over the age of 50 who regularly have theirprostate examined is significantly less than 0.33. A random sample of 737 men over the age of 50 foundthat 206 have their prostate regularly examined. Do the sample data provide convincing evidence tosupport the claim? Test the relevant hypotheses using a 5% level of significance. Give answer to at least 4decimal places.What are the correct hypotheses?

New Orleans' Coca Cola bottling center wants to determine whether the mean amount of product in a 12 oz can of Coke is actually 12 ounces. Thus, the null and alternative hypotheses are Ho: mu is equal to 12 ounces Ha: mu is not equal to 12 ouncesYou want to be extra sure that you aren't underfilling (which would open you up to a lawsuit). Being risk averse, you set out to conduct a hypothesis test at a stringent 99% level. Fill rates are distributed Normally. You take a sample of 50 different Coke cans and carefully measure the amount of product. From this sample, you calculate an avg fill of 12.3 ounces, with a standard deviation of 0.75 ounces. Do you reject or not-reject the null hypothesis? Group of answer choices Do not reject the null hypothesis. Reject the null hypothesis.
Based on historical data in Oxnard college, we believe that 33% of freshmen do not visit their counselors regularly. For this year, you would like to obtain a new sample to estimate the proportiton of freshmen who do not visit their counselors regularly. You would like to be 98% confident that your estimate is within 4.5% of the true population proportion. How large of a sample size is required? Do not round mid-calculation. n =

practice question #9. A sample of 340 randomly selected adult Americans were asked this question: “Do you use a remote start for your vehicle during the Winter?” 117 answered “yes.” Based on this, is it reasonable to assume that more than 33% of adult Americans use a remote start during the Winter? Set up the relevant hypotheses, show the sample is appropriate for this test, calculate a test statistic and P-value, decide whether or not to reject the null hypothesis, and put your conclusion in context of the scenario. Round P-value to 4 decimal places and test statistic to 2 decimal places. Use ∝= .05. Hypotheses: Address appropriateness of size: Value of test statistic: ________________________________ P-value: ________________________________ State your conclusion in the context of the problem.
The test statistic for this hypothesis? The p value?
