A melting point test of n = 10 samples of a binder used on manufacturing a rocket propellant resulted in = 154.2 °F. Assume thatthe melting point is normally distributed with o = 1.5 °F.For (b) and (c), round your answers to 4 decimal places (e.g. 98.7654). For (d). give an integer answer.(a) Test Ho : μ = 155 versus H₁:μ ‡ 155 using a = 0.01.Ho(b) What is the P-value for this test? Use a z-score with two decimal places.(c) What is the B-error if the true mean is μ = 150? Assume that a = 0.01. i(d) What value of n would be required if we want <0.1 when μ = 150? Assume that a = 0.02.i

We are given an approximate value of n is 22/7 = 3.1428571 and true value is 3.1415926. Calculate true error (round to 7 decimal places) and true percent relative error (round to 2 decimal places). Note: Separate your answers by a comma. Write your answer for true error first, followed by true percent relative error. Ex. XXXX,yyyy
The often-repeated conventional wisdom is that male police officers die at a significantly younger age than the rest of the male population. The origin of this statement often is attributed to a study by the U.S. Department of Justice, but the agency says it never conducted such a study. The issue is a key to police budget and benefit debates across the country, therefore you decide to examine this issue. You collect data on a sample of 18 male current and former police officers who died in the last year and find that the mean age at the time of death is 73 with a SS = 1224. You know that for the mean of death for all males who died in the last year is 77. Using an alpha of .05, test the hypothesis that male police officers die, on average, at a age younger age than the population of males. Step 1: 3a. Identify the null hypothesis. Type a - 1 here a. Ho: u > 73 b. Ho: µ77 h. Ho: u 77 j. Ho: u73 b. Hi: u73 d. Hi: µ 77 MacBook Air
Radon is a gas emitted from the ground that can collect in houses in buildings. At certain levels it can cause lung cancer. Radon concentrations are measured in picocuries per liter (pCi/L). A radon level of 4 pCi/L is considered “acceptable” Radon levels in a house vary from week to week. In one house, a sample of 6 weeks had the following readings for radon level (in pCi/L): 1.9 2.8 3.9 3.9 4.2 5.7 Find the variance and standard deviation (definitional formula). Show your work using a table.
