(b) A study of the properties of metal plate-connected trusses used for roof support yielded the axial-stiffness index (kN/m) for plate lengths 0.10, 0.15, 0.20, 0.25, and 0.30 m as shown in Table Q2(b). Does variation in plate length have any effect on true average axial stiffness? State and test the relevant hypotheses using analysis of variance (ANOVA) with a = 0.01. Display your results in an ANOVA table.

An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 120 engines and the mean pressure was 5 lbs/square inch. Assume the variance is known to be 1. If the valve was designed to produce a mean pressure of 5.1 lbs/square inch, is there sufficient evidence at the 0.02 level that the valve performs below the specifications? State the null and alternative hypotheses for the above scenario.
Why is it impossible to calculate a negative F value when using an Analysis of Variance to test a hypothesis?
An experiment was conducted to compare alcohol content of a cleaning product on two differentproduction lines. Production was monitored five times a day. The data are shown in Table 3.Assume both populations are normally distributed. It is suspected that production line 1 is notproducing as consistently as production line 2 in terms of the alcohol content. Test this claim atsignificance level 0.05 by assuming that the two population variances were equal. production line 1 0.48 0.39 0.42 0.52 0.40 production line 2 0.38 0.37 0.39 0.41 0.38
In building an arena, steel bars with mean ultimate tensile strength of 400 megapascal(Mpa) with a variance of 81 Mpa were delivered by the manufacturer. The project engineer tested 50 steel bars and found out that the mean ultimate tensile strength is 390 MPa. The decision for the extension of the contract with the manufacturer depends on the engineer. Test the hypotheses whether or not there is no significant difference between the two means using a two-tailed test with a=0.01. 1. What are the appropriate hypotheses for the two-tailed test? 2. What is the test statistics to be used and the reasons for its selection? 3. What is the critical value of c? 4. What is the value of the test statistic or the computed value? 5. Formulate a conclusion about the given situation.
A study was undertaken to compare the average high-density lipoprotein (HDL) levels of normal and obese adults in a certain community. HDL levels of a random sample of adults from this community were measured (in milligrams per deciliter or mg/dL) and presented below. Assume that the HDL levels of both the normal and obese adults follow the normal distribution with unknown but equal population variances. Is there a significant difference between the average HDL levels of normal and obese adults? Use a 5% level of significance.

The melting points of two alloys used in formulating solder were investigated by melting 21 samples of alloy 1 and 16 samples of alloy 2. The sample mean and standard deviation for alloy 1 was x1 = 420.48 s1 = 2.34 and for alloy 2 they were overline x2 = 425 and s2 = 2.5 .Do the sample data support a claim that both alloys have the same variance of melting point? Use alpha = 0.05
