Make a normal probability plot of the residuals and discuss its appearance. Inspect the residual plots to check for heteroscedasticity and report your conclusion.
Vertical banded gastroplasty is a surgical procedure that reduces the volume of thestomach in order to produce weight loss. In a recent study, 82 patients with Type 2 diabetes underwent this procedure, and 59 of them experienced a recovery from diabetes. Does this study provide convincing evidence that the percentage of those with diabetes who undergo this surgery will recover from diabetes differs from 74%? State the null and alternate hypotheses and use the α=0.05 level of significance and thecritical value method
Poly(3-hydroxybutyrate) (PHB), a semicrystalline polymer that is fully biodegradable and biocompatible, is obtained from renewable resources. From a sustainability perspective, PHB offers many attractive properties though it is more expensive to produce than standard plastics. The accompanying data on melting point (°C) for each of 12 specimens of the polymer using a differential scanning calorimeter appeared in an article. (b) the sample variance s2 from the definition [Hint: First subtract 180 from each observation.] (c) the sample standard deviation (d) s2 using the shortcut method
Determine the kurtosis if the data given is a sample. Use 4 decimal places
Vertical banded gastroplasty is a surgical procedure that reduces the volume of the stomach in order to produce weight loss. In a recent study, 82 patients with Type 2 diabetes underwent this procedure, and 59 of them experienced a recovery from diabetes. Does this study provide convincing evidence that more than 60% of those with diabetes who undergo this surgery will recover from diabetes? Use a 5% level significance.
Production managers on an assembly line must monitor the output to be sure that the level of defective products remains small. They periodically inspect a random sample of the items produced. If they find a significant increase in the proportion of items that must be rejected, they will halt the assembly process until the problem can be identified and repaired. State the hypotheses: In this context, what is a type I error? What is a consequence of this error? In this context, what is a type II error? What is a consequence of this error? Which type of error would the factory owner consider more serious? Which type of error might customers consider more serious?
A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a storm is in progress with a severe storm class rating. Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down or getting worse. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis? Is the P-value area on the left, right, or on both sides of the mean?

H1 : μ is less than 16.4 feet; the P-value area is on the right of the mean b. H1 : μ is not equal to 16.4 feet; the P-value area is on the right of the mean c.

A drug manufacturer thinks that the average additive concentration in drugs should not exceed 0.03. It is known that the additive concentration is normally distributed and its standard deviation is 0.004. 36 drugs were randomly selected and controlled, and the average additive concentration was found to be 0.0309. At α = 0.01 significance level, whether the average additive concentration exceeds 0.03; a) Set your hypothesis h0 and h1.b) Show the rejection region by scanning on the distribution curve and expressing the critical value.c) Calculate the test statistics.d) Calculate the p-value for the test.e) Write down and interpret the decision you made as a result of the hypothesis test.
A random sample of data has a mean of 75 and a variance of 25.a. Use Chebyshev’s theorem to determine the percent of observations between 65 and 85.b. If the data are mounded, use the empirical rule to find the approximate percent of observations between 65 and 85.
Some shrubs have the useful ability to resprout from their roots after their tops are destroyed. Fire is a particular threat to shrubs in dry climates, as it can injure the roots as well as destroy the aboveground material. One study of resprouting took place in a dry area of Mexico. The investigation clipped the tops of samples of several species of shrubs. In some cases, they also applied a propane torch to the stumps to simulate a fire. Of 17 specimens of a particular species, 6 resprouted after fire. Estimate with 95% confidence the proportion of all shrubs of this species that will resprout after fire.Interval:
State the null hypothesis if traffic department wants to test whether the modification reduces the number of traffic accidents in Central. Continue from part a, state the corresponding alternative hypothesis of the test. Continue from part a, calculate the test statistics of the test. Continue from part c, what is the critical value of the test if the significant level is 1%? According to the test, is it reasonable to conclude that the modification reduced the number of traffic accidents?
