a) Genenesis Dispensary is contemplating of opening a new branch in Mwanza. If the medical for medical service is favourable, Genesis could realize a net profit of Tsh.100 million. On the other hand, if the market turn out to be unfavourable, it can end up losing Tsh. 40 million. Of course, Genesis may opt not to persue this option of expanding its operations. In the absence of data from which to base its decision, te best guess for Gensis is equally likely that the dispensary will either be successful or unsuccessful Required: i) Use the decison tree approach, what decison should Genesis Dispensary take b) Market research firm named, Easy Market Access approach Genesis with an offer to undertake a study of Mwanza medical service market at a fee of Tsh. 5 million. Easy Market Access claims that their experience enables them to use Bayes’ Theoremn to make the following statements about different state of the market: ▪ Provide that the study is favourable, the probability of favourable…
Ms. Tina is the accountant in the Walton Industries. She believes that the current cash-flowproblem at Walton is due to the slow collection of accounts receivable. She believes that morethan 60 percent of the accounts are in arrears more than three months. A random sample of200 accounts showed that 140 were more than three months old. At the 0.05 significancelevel, can she conclude that more than 60 percent of the accounts are in arrears for more thanthree months?

A researcher is concerned that his new antihypertensive medication may be causing insomnia in some of his patients. Suppose he gathers an SRS of 65 patients treated with the study drug with a sample average of 6.6 hours of sleep and a σ=1.1. Assuming that insomnia can be quantified as an average of 4.5 hours of sleep, can we determine with 95% confidence that his drug avoids diagnosis of insomnia as a side-effect?
Suppose that a portfolio consists of two assets A and B whose returns are givenby RA = RM + uA and RB = 2RM + uB, where RM is the market return, which isuncertain, and where uA and uB are uncorrelated shocks with expected value of zeroand variance of 0.01. Suppose RM has expected value of 0.05 and a variance of 0.01. Calculate theexpected return and variance of both assets A and B.

A real estate agent believes that the value of houses in the neighborhood she works in has increased from last year. To test this claim, she selects random houses in this neighborhood and compares their estimated market value in the current year to their estimated market value in the previous year. Suppose that data were collected for a random sample of 8 houses, where each difference is calculated by subtracting the market value of the previous year from the market value of the current year. Assume that the values are normally distributed. The agent uses the alternative hypothesis Ha:μd>0. Using a test statistic of t≈7.496, which has 7 degrees of freedom, determine the range that contains the p-value.

36. Dilbert’s Department Store is trying to determine howmany Hanson T-shirts to order. Currently the shirtsare sold for $21, but at later dates the shirts will beoffered at a 10% discount, then a 20% discount, thena 40% discount, then a 50% discount, and finally a60% discount. Demand at the full price of $21 is believed to be normally distributed with mean 1800 andstandard deviation 360. Demand at various discountsis assumed to be a multiple of full-price demand.These multiples, for discounts of 10%, 20%, 40%,50%, and 60% are, respectively, 0.4, 0.7, 1.1, 2, and50. For example, if full-price demand is 2500, thenat a 10% discount customers would be willing to buy1000 T-shirts. The unit cost of purchasing T-shirtsdepends on the number of T-shirts ordered, as shownin the file P10_36.xlsx. Use simulation to determinehow many T-shirts the company should order. Modelthe problem so that the company first orders somequantity of T-shirts, then discounts deeper and deeper,as necessary, to sell…
The management of a supermarket wants to adopt a new promotional policy of giving free gift to every customer who spends more than a certain amount per visit at this supermarket. The expectation of the management is that after this promotional policy is advertised, the expenditure for all customers at this supermarket will be normally distributed with mean 400 £ and a variance of 900 £2. 2) In a sample of 250, find the count that corresponds to the interquartile range. 3) Based on your answer in and without any calculation, if the mean changed to be 500 £, would the probability be the same?
The proportion p of residents in a community who recycle has traditionally been 70%. A policy maker claims that the proportion is less than 70% now that one of the recycling centers has been relocated. If 159 out of a random sample of 230 residents in the community said they recycle, is there enough evidence to support the policymaker's claim at the 0.10 level of significance?Perform a one-tailed test. Then complete the parts below.Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis H0 and the alternative hypothesis H1. H0: H1: (b) Determine the type of test statistic to use. ▼(Choose one) (c) Find the value of the test statistic. (Round to three or more decimal places.) (d) Find the p-value. (Round to three or more decimal places.) (e) Is there enough evidence to support the policy maker's claim that the proportion of residents who…
