a. Let X be a single observation from a normal distribution with mean and withvariance 02, where > 0. Find the maximum likelihood estimator of 0².b. Let X₁, X2, . . . , Xn be independent identically distributed random variablesfrom a N(μ, o2) distribution where the variance o² is known. We want to testHo : μ = μo against H, : μ + μο(i) Derive the likelihood ratio test.(ii) Let A be the likelihood ratio. Show that -2log A is a function of (X - μo).Assuming that Ho is true, find P(-2 log > 3.84).

The normal distribution is the most commonly used continuous distribution. The random variable which…

A coffee-dispensing machine is supposed to deliver 8 ounces of liquid into each paper cup, but a consumer believes that the actual mean amount is less. The consumer obtained a sample of 49 cups of the dispensed liquid with average of 7.75 ounces. If the sample variance of the dispensed liquid delivered per cup is 0.81 ounces, and α=0.05, the appropriate decision is ________. Question 6Select one: a. reject the 8-ounces claim b. reduce the sample size c. increase the sample size d. fail to reject the 8-ounces claim

A researcher takes sample temperatures in Fahrenheit of 16 days from Miami and 14 days from Atlanta. Use the sample data shown in the table. Test the claim that the mean temperature in Miami greater than the mean temperature in Atlanta. Use a significance level of α=0.10α=0.10.Assume the populations are approximately normally distributed with unequal variances.Note that list 1 is longer than list 2, so these are 2 independent samples, not matched pairs.
