No generated AI please. Let Y₁, Y₂, Yn denote a random sample from a normal distribution withknown mean and unknown variance σ².μ4 Find the most powerful a-level test of Ho: σ² = σ² vs. H₁: σ² = σ2, whereσ² > 0.Show that this test is equivalent to a x2 test. [Hint: Recall that for Z1, Z2,"Zn independent standard normal random variables,distribution with n df.]Zhas a x²2. Is the test from part (b) uniformly most powerful (UMP) for Hå: σ² > σ²?

COVID-19 (novel corona virus) took the world by surprise in late 2019. By early 2020, nearly all countries worldwide were affected.Early reports from the US Centers for Disease Control and Prevention (CDC) estimated that approximately 3% of infected patients in the United States between the ages of 55 and 64 had died. This figure is known as the mortality rate of the virus for this age group. Suppose a sample of 1120 infected patients in the United States between the ages of 55 and 64 were randomly selected and 34 of the patients were known to have died. Use the p-value method to determine if the sample data support the conclusion that the mortality rate of patients between the ages of 55 and 64 is greater than 3%. Let α=0.01State the null and alternative hypothesis for this test. H0= H1= Determine the test statistic for the hypothesis test. Round the solution to two decimal places. = Determine the p-value for the hypothesis test. Round the solution to four decimal places. = Determine…

An aerosolized vaccine for measles was developed in Mexico and has been used on 44 million children since 1980. Aerosolized vaccines have the advantages of being able to be administered by people without clinical training and do not cause injection‐associated infections. The percentage of children developing an immune response to measles after receiving the subcutaneous injection of the vaccine is 95%,95%, and for those receiving the aerosolized vaccine, it is 85%85% . There are 2020 children to be vaccinated for measles using the aerosolized vaccine in a small rural village in India. We are going to count the number who developed an immune response to measles after the vaccination. (b) What is the probability that at least one child does not develop an immune response to measles after receiving the aerosolized vaccine? (Enter your answer as a proportion rounded to four decimal places.)

One of its transmissionassemblies requires part #HD234, purchased from a supplier within the same industrial park. Because ofthe close proximity of its supplier, the lead me for part #HD234 is negligible.The demand for part #HD234 varies according to the orders received from the automobile manufacturer.The requirements schedule for the next 10 periods is shown below: Period 1 2 3 4 5 6 7 8 9 10 Total Demand 115 50 175 95 150 225 75 70 40 20 1,015 This requirements schedule is considered fairly typical. Furthermore, the cost of placing an order with anearby supplier is $85.00, the purchase cost is $65.00, and the holding cost fracon is 0.01 per period.Mohawk is in the process of assessing different lot-sizing policies.
