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.

QUESTION 3 The Research Unit for Cecilion Supermart conducted an experiment to estimate the strength of thecarrier bag from the starch-based biofilms made from two different jicamas (sengkuang) of type Aand type B. However, the researcher claims that jicama type A produces more strength comparedto type B. To support this claim, 10kg weight item was put into 100 carrier bags made from jicamatype A and 200 carrier bags made from jicama type B were randomly selected. As a result, 8 bagsfrom jicama type A burst while 12 bags from jicama type B burst. Calculate a 95% confidenceinterval for the difference in true proportion of the carrier bags which burst between jicama type Aand type B. Give comment on the parameter estimate.
QUESTION 19 To study whether the students at a university are more or less satisfied with the current food service compared to the previous food service, a sample of 90 current students is taken and finds that 37 are satisfied with the current food service. A similar survey was taken for the previous food service in which 89 students surveyed found that 40 were satisfied with the previous food service. When testing the hypothesis (at the 5% level of significance) a higher percentage of students were satisfied with the previous food service than with the current food service, what is the test statistic? (please round your answer to 2 decimal places)

Figure 1 shows the results of the statistical test without interaction term between Region and Design (aov1), and the statistical test with interaction term between Region and Design (aov2) as R output for this problem. Figure 1. (Image Uploaded) R output of model results for two statistical models, one without an interaction term between Design and Region (aov1) and one with interaction term between Design and Region (aov2). Using a significant at the significance level alpha = 0.05, based on Figure 1 which statement is correct? A.) The model without interaction (aov1) shows that the factors Design and Region are not significant with regards to their impact on survey responses at the selected significance level. B.) The model with interaction (aov2) shows that interaction term between Design and Region is significant with regards to the impact on survey responses at the selected significance level. C.) Using the model with interaction (aov2) results, we fail…
A test of body reaction to the Malaysian citizens who have taken their vaccine was conducted. Selected citizens who got side effect are categorised according to their blood type and the type of vaccine received. From a sample of 250 citizens, 150 of them were administered with Sinovac while the rest received AstraZeneca. Table 4 shows the number of citizens who had side effect after being vaccinated. Type of vaccine Blood type A B AB O Sinovac 50 M 50 20 AstraZeneca 30 20 20 N Does different blood type among people who had side effect relate to the type of vaccinereceived at A=0.025?

An investigation was conducted into the dust content in the flue gases of two types of solid-fuel boilers. Thirteen boilers of type A and nine boilers of type B were used under identical fueling and extraction conditions. Over a similar period, the quantities of dust were deposited in similar traps inserted in each of the twenty-two flues. Presented below are the collected dust content (in grams) given the source broiler type.

27. An article in Radio Engineering and Electronic Physics (1980, Vol. 25, pp. 74-79) investigated the behavior of a stochastic generator in the presence of external noise. The number of periods was measured in a sample of 100 trains for each of two different levels of noise voltage, 100 and 150 mV. For 100 mV, the mean number of periods in a train was 7.9 with s1 = 2.6. For 150 mV, the mean was 6.9 with s2 = 2.4. Use α = 0.01 and assume that each population is normally distributed and the two population variances are equal. (a) It was originally suspected that raising noise voltage would reduce mean number of periods. Do the data support this claim? (b) Calculate a confidence interval to answer the question in part (a).
A local church is interested in determining how length of residence in the present community relates to church attendance.

Consider the two-component system of Conceptual Problem 4.6. Further more, suppose that a single repair person starts the system repair as soon as the system fails. The repair time of each component is an Exp(a) random variable. The system is turned on when both components are repaired. Assume that shocks have no effect on the components unless the system is on. Model this as a CTMC.
