- stion 3 of 14 <. You and a group of friends are going to a five-day outdoor music festival during spring break. You hope it does not rain during the festival, but the weather forecast says there is a 45% chance of rain on the first day, a 55% chance of rain on the second day, a 10% chance of rain on the third day, a 10% chance of rain on the fourth day, and a 5% chance of rain on the fifth day. Assume these probabilities are independent of whether it rained on the previous day or not. What is the probability that it does not rain during the entire festival? Express your answer as a percentage to two decimal places.Pain after surgery: In a random sample of 42 patients undergoing a standard surgical procedure, 15 required medication for postoperative pain. In a random sample of 90 patients undergoing a new procedure, only 11 required pain medication. Part: 0 / 2 Part 1 of 2 (a) Construct a 95% confidence interval for the difference in the proportions of patients needing pain medication between the old and new procedures. Let p, denote the proportion of patients who had the old procedure needing pain medication. Use tables to find the critical value and 1 round the answer to at least three decimal places. A 95% confidence interval for the difference in the proportions of patients needing pain medication between the old and new procedures isUse the likelihood ratio to finda 95% confidence interval for theta based on data in Table 5.1.

The past 2 times I've asked, no one's read my message.Say that on average teenagers eat 10 slices of pizza each week, with a 95% confidence interval of (8-12). We take a sample of teenagers and find that this group eats an average of 6 slices each week. What can we say about the teenagers in the sample in relation to the confidence interval?have 15mins help ASAP!When finding the upper bound, UU, of a confidence interval given the lower bound, LL, and the margin of error, EE, we use the formula U=L+2EU=L+2E. Find the upper bound for the proportion of babies that are born preterm if the lower bound is L=0.364L=0.364 and the margin of error is E=0.176E=0.176. Round your answer to 3 decimal places.U=Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 678 randomly selected adults showed that 50.5% of them would erase all of their personal information online if they could. Make a subjective estimate to decide whether the results are significantly low or significantly high, then state a conclusion about the original claim. The results v significantly v so there V sufficient evidence to support the claim that most adults would erase all of their personal information online if they could.(only if possible, preferably in minitab, but you can do it manully)Confidence in banks: A poll conducted in 2012 asked a random sample of 1217 adults in the United States how much confidence they had in banks and other financial institutions.

Can you conclude that the economist's claim is true? Use both =α0.05 and =α0.10 levels of significance and the P-value method with the TI-84 Plus calculator.
