An important quality characteristic used by the manufacturers of ABC asphalt shingles is the amount of moisture the shingles contain when they are packaged. Customers may feel that they have purchased a product lacking in quality if they find moisture and wet shingles inside the packaging.   In some cases, excessive moisture can cause the granules attached to the shingles for texture and colouring purposes to fall off the shingles resulting in appearance problems. To monitor the amount of moisture present, the company conducts moisture tests. A shingle is weighed and then dried. The shingle is then reweighed, and based on the amount of moisture taken out of the product, the pounds of moisture per 100 square feet is calculated. The company claims that the mean moisture content cannot be greater than 0.35 pound per 100 square feet.
The file (A & B shingles.csv) includes 36 measurements (in pounds per 100 square feet) for A shingles and 31 for B shingles.

3.1. For the A shingles, form the null and alternative hypothesis to test whether the population mean moisture content is less than 0.35 pound per 100 square feet.

3.2. For the B shingles, form the null and alternative hypothesis to test whether the population mean moisture content is less than 0.35 pound per 100 square feet.

3.3. Do you think that the population means for shingles A and B are equal?
Form the hypothesis and conduct the test of the hypothesis.
What assumption do you need to check before the test for equality of means is performed?

3.4. What assumption about the population distribution is needed in order to conduct the hypothesis tests above?

And you are performing a 1-sample t test… A) How many data points would be needed if you wanted to detect a difference of 5 minutes. Assume that alpha is 0.05. Beta is 0.10 (Power is .9). B) Given that you have already collected 40 data points, what was the Power of the test? Assume alpha is 0.05 and the difference is 5 again. C) Suppose you would like to look at several possibilities at once…Find the sample size needed if the difference is 3, 4 and 5 minutes while the power is 0.7, 0.8, and 0.9.

Q1. Roller bearings are subject to fatigue failure caused by large contact loads. The

problem of finding the location of the maximum stress along the x axis can be shown to be

equivalent to maximizing the function:

= + x

With the aid of the secant method, use xo=0.98 and x1=0.7 to determine to within 10^-5 the

value of x that maximizes f(x).

Q 2. In an LRC series circuit, the impressed voltage E(t) and the charge q(t) on the

capacitor are related to each other by the linear second-order ordinary differential equation,

where L is the inductance, R is the resistance and C is the capacitance. Suppose we measure

the charge on the capacitor for several values of t and obtain

where t is in seconds, q is in coulombs, the inductance L is a constant 0.5h , the resistance R

is 0.3Ω and the Capacitance is 0.01 f . Approximate the voltage E(t) when t = 1.525, 1.55 and

1.575.

TABLE 10-16

A realtor wants to compare the average sales-to-appraisal ratios of residential properties sold in four neighborhoods (A, B, C, and D). Four properties are randomly selected from each neighborhood and the ratios recorded for each, as shown below.
A: 1.2, 1.1, 0.9, 0.4 C: 1.0, 1.5, 1.1, 1.3
B: 2.5, 2.1, 1.9, 1.6 D: 0.8, 1.3, 1.1, 0.7

Interpret the results of the analysis summarized in the following table:



Referring to Table 10-16, what should be the decision for the Levene’s test for homogeneity of variances at a 5% level of significance?

Group of answer choices

Do not reject the null hypothesis because the p-value is larger than the level of significance.

Reject the null hypothesis because the p-value is larger than the level of significance.

Do not eject the null hypothesis because the p-value is smaller than the level of significance.

Reject the null hypothesis because the p-value is smaller than the level of significance.
