Please help correct part C) thanks The burning rates of two different solid-fuel propellants used in aircrew escape systems are being studied. It is known that bothpropellants have approximately the same standard deviation of burning rate; that is, a1 = 0₂ = 3 cm/s. From a random sample of sizen₁ = 20 and n₂ = 20, we obtain x₁ = 18.02 cm/s and X₂ = 24.39 cm/s.Good. Since the value of the test statistic falls in the rejection region, we reject Ho Ho at a = 0.05.a = 0.05.(a) Test the hypothesis that both propellants have the same mean burning rate.

An article compared the dielectric constants between two types of asphalt, HL3 and HL8, commonly used in pavements. For 42 specimens of HL3 asphalt the average dielectric constant was 5.92 with a standard deviation of 0.15, and for 37 specimens of HL8 asphalt the average dielectric constant was 6.05 with a standard deviation of 0.16. Can you conclude that the mean dielectric constant differs between the two types of asphalt? Find the P-value and state a conclusion. The P-value is . Round the answer to four decimal places. We (Click to select) cannot can conclude that the mean dielectric constant differs between the two types of asphalt.

To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 41 feet. Assume the population standard deviation is 4.6 feet.The mean braking distance for Make B is 42 feet. Assume the population standard deviation is 4.4 feet. At α=0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles? Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) through (e). (a) Identify the claim and state Ho and Ha. What is the claim?

A biologist knows that the average length of a leaf of a certain plant is 4 inches. The standard deviation of the population is 0.6 inch. A sample of 20 leaves of that type of plant given a new type of plant food had an average length of 4.2 inches. At α = 0.01, is there reason to believe that the new food is responsible for a change in the growth of leaves?
