In 2014, the Centers for Disease Control and Prevention reported the percentage of people 18of age and older who smoke. Suppose that a study designed to collect new data on smokers andnonsmokers uses a preliminary estimate of the proportion who smoke of 0.30.a. How large a sample should be taken to estimate the proportion of smokers in the population witha margin of error of 0.02? Use 95% confidence. Remove all commas from your answer beforesubmitting. Round your answer to next whole number.b. Assume that the study uses your sample size recommendation in part (a) and finds 520smokers. What is the point estimate of the proportion of smokers in the population? (to 4 decimals)c. What is the 95% confidence interval for the proportion of smokers in the population? (to 4decimals)X

Given P=0.30 Margin of error =0.02 Confidence level 95%

Past surveys showed that 44.2% of Filipino households have pets. A recent survey reported that 516 of the 1200 Filipino households have pets. Does this indicate that the proportion of Filipino households who have pets has decreased? Use a 5% level of significance. A. Perform a complete test of hypothesis. B. Select here the conclusion for this test of hypothesis. The proportion of Filipino households who have pets has decreased. There is no sufficient evidence to say that the proportion of Filipino households who have pets has decreased.

UBS Wealth Management UK periodically ask their customers to evaluate their financial consultants and services. The higher the customer rating, the better the perceived service. The maximum rating is 7. Independent samples of two financial consultants are given below. Consultant A has 10 years' experience, Consultant B has 1 years' experience. Use α = 0.05 and test to see whether the consultant with more experience has the higher population mean service rating. Consultant A Consultant B N1 = 16 N2 = 10 Mean1 = 6.82 Mean2 = 6.25 S1= 0.64 S2 = 0.75 State the null and alternative hypothesis, Compute the value of the test statistic. What is the p-value? What is your conclusion?
A poll found that 59% of a sample of 1020 teens in a certain large country go online several times a day. (Treat this sample as a simple random sample.) Complete parts a through e below. Find the margin of error for this poll if we want 90% confidence in our estimate of the percent of teens in the country who go online several times a day. Explain what the margin of error means. If instead we need to be 95% confident, will the margin of error be larger or smaller? Explain. Find that margin of error.
