Use the data given to test the following hypotheses. Assume the data are normally distributed in thepopulation.A manufacturing company produces valves in various sizes and shapes. One particular valve plate is supposed to have a tensile strength of 5 pounds per millimeter (lbs/mm).The company tests a random sample of 42 such valve ...The following data (in pounds),which were selected randomly from a normally distributed population of values, represent measurements of a machine part that is supposed to weigh, on average,8.3 pounds.Use these data and α ...Suppose you are testing H0: p = .45 versus Ha: p > .45.A random sample of 310 people produces a value of p̂ = .465. Use α = .05 to test this hypothesis.Test each of the following hypotheses by using the given information. Assume the populations are normally distributed.a.
