Use a = 0.05.(c)Perform a pair-wise comparison of the means using the Duncan's multiplerange test. Use a = 0.05. Question 2The durability of a plastic product is directly affected by the hardness of the plastictypes used. Plastic hardness which is measured with the Durometer Hardness testgoes between 0 and 100. A higher number represents a harder plastic. Acomparative test is conducted to investigate the quality of the plastic based on theirhardness from 3 different factory sources. The test is conducted with 6 differentplastic types acquired from each factory source. The types of plastic are sortedbased on the nature of hardness in ascending order.

If there is evidence that the percentage differs significantly from this target, then adjustments will be made to the game. To investigate, a random sample of 100 players is selected from the large population of all players. Of these players, 19 win a large prize. The question of interest is whether the data provide convincing evidence that the true proportion of players who win this game differs from 0.10. The computer output gives the results of a z-test for one proportion. Test and CI for One Proportion Test of p= 0.1 vs p = 0.1 Sample X N Sample 1 19 100 Р 0.19 What conclusion should be made at the a = 0.05 level? O Because the P-value < a = 0.05, there is convincing evidence that the true proportion of players who win this game differs from 0.10. O Because the P-value < a = 0.05, there is…

STATISTICAL ANALYSIS (No long explanation needed. Rate will be given and write the complete solutions.) CI on Mean, Variance Unknown, Prediction and Tolerance Interval A CNC (computer numerical control) machine produces iron automobile crankshafts. Samples are measured and the inner diameter are found to be 1.01, 0.97, 1.03, 1.04, 0.99, 0.98, 0.99, 1.01, and 1.03 centimeters. For all computations, assume an approximately normal distribution. The sample mean and standard deviation for the given data are = 1.0056, and s = 0.0246. Find a 99% confidence interval on the mean of diameter. Compute a 99% prediction interval on a measured diameter of a single crankshaft piece taken from the machine. Find the 99% tolerance limits that will contain most of the metal pieces produced by the CNC machine. Choose the correct answer. a. CI on the mean: 0.970 < μ < 1.9845.
