The admitting office at Sisters of Mercy Hospital wants to be able to inform patients of the average level of expenses they can expect per day. Historically, the average has been approximately $1280. The office would like to know if there is evidence of a decrease in the average daily billing. Seventy-seven randomly selected patients have an average daily charge of $1263 with a standard deviation of $272. Conduct a hypothesis test to determine whether there is evidence that average daily charges have decreased at a significance level of α = 0.05. Assume the population of daily hospital charges is approximately normally distributed. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Ho : μ = 1280 Ha H 1280

Quit smoking: A recent study reported that in a sample of 234 European-American HIV-positive smokers, 105 of them had used a nicotine patch to try to quit smoking, and in a sample of 81 Hispanic-American HIV-positive smokers, 25 had used a nicotine patch. Can you conclude that the proportion of patch users is greater among European-Americans? Let p₁ denote the proportion of European-Americans who used the patch. Use the a=0.01 level of significance.

HOW Do I solve this in EXCEL In 2016, the Better Business Bureau (BBB) settled 80% of complaints they received in the US. Suppose you have been hired by the BBB to investigate the complains they received this year involving new car dealers. You plan to select a sample of new car dealer complaints to estimate the proportion of complaints the BBB is able to settle. Assume the population proportion of complaints settled for new car dealers is 0.8, the same as the overall proportion of complaints settled in 2016. Suppose you select a sample of 200 complaints involving new car dealers. Show the sampling distribution of pbar. Based on a sample of 200 complaints, what is the probability that the sample proportion will be within 0.04 of the population proportion? Suppose you select a sample of 450 complaints involving new car dealers. Show the sampling distribution of pbar. Based on the smaller sample of only 450 complaints, what is the probability that the sample proportion will be within…
