Suppose a researcher wants to test if the average diastolic blood pressure in African-Americans is different than the average diastolic blood pressure in the general population. Note that the average diastolic blood pressure in the general population is 70 mmHG. The researcher retains the null hypothesis, so she therefore concludes...

The mean for the number of pets owned per household was 2.1. A poll of 1023 householdsconducted this year reported the mean for the number of pets owned per household to be 2.Assuming σ = 1.1, is there sufficient evidence to support the claim that the mean number ofpets owned has changed since at the α = 0.05 level of significance? Use the p-value approach and clearly specify each step.

A random sample of 46 adult coyotes in a region of northern Minnesota showed the average age to be x=2.07 years with sample staved deviation s=0.88 years. However, it is thought that the overall population mean age of coyotes is u=1.75. Do the sample data indicate that coyotes in this region of northern Minnesota tend to live longer than the average of 1.75 years? Use a=0.01
An engineer wants to compare the tensile strengths of steel bars that are produced using a conventional method and an experimental method. (The tensile strength of a metal is a measure of its ability to resist tearing when pulled lengthwise.) To do so, the engineer randomly selects steel bars that are manufactured using each method and records the following tensile strengths (in Newtons per square millimeter). At α=.10, can the engineer claim that the experimental method produces steel with greater mean tensile strength? Should the engineer recommend using the experimental method? First use the F test to determine whether or not to use equal variances in choosing the model.(??? ????? ?? ???? ?̅ ??? ? ??? ???ℎ ???ℎ??)
