Textbook Question
Chapter 14.2, Problem 1Q

Recall the data in Question 8.2.9 giving the sizes of ten gorilla groups studied in the Congo. Is it believable that the true median size, μ ¯ of all such groups is 9? Answer the question by finding the P-value associated with the null hypothesis H 0 : μ ¯ = 9. Assume that H 1 is two-sided. (Note: Tabulated below is the binomial pdf for the case where n = 10 and p = 1 2 )

An article includes the accompanying data on compression strength (lb) for a sample of 12-oz aluminum cans filled with strawberry drink and another sample filled with cola. Beverage   Sample  Size   Sample  Mean   Sample  SD Strawberry Drink 10 535 24 Cola 10 559 15 Does the data suggest that the extra carbonation of cola results in a higher average compression strength? Base your answer on a P-value. (Use  ? = 0.05.)   State the relevant hypotheses. (Use ?1 for the strawberry drink and ?2 for the cola.)

A sample of 12 radon detectors of a certain type was selected, and each was exposed to 100 pCi/L of radon. The resulting readings were as follows: 104.3 89.6 89.9 95.6 95.2 90.0 98.8 103.7 98.3 106.4 102.0 91.1   a)Does this data suggest that the population mean reading under these conditions differs from 100? State and test the appropriate hypotheses using =.05.   b) Suppose that prior to the experiment, a value of teta=7.5 had been assumed. How many determinations would then have been appropriate to obtain beta=.10 for the alternative u=95 ?

    In my regression output using Hayes Model 1 I have the following results. Would it be safe to say that the following assumption is correct? 95% CI is [.036, .196] not statistically significant, But given that  (p = .176) is greater than p=.005, we reject the null hypothesis.  (b3) of .080, t = 1.36, p = .176, 95% CI [.036, .196].
