In Exercises 5–20, conduct the hypothesis test and provide the test statistic and the P-value and /or critical value, and state the conclusion.
5. Testing a Slot Machine The author purchased a slot machine (Bally Model 809) and tested it by playing it 1197 times. There are 10 different categories of outcomes, including no win, win jackpot, win with three bells, and so on. When testing the claim that the observed outcomes agree with the expected frequencies, the author obtained a test statistic of χ2 = 8.185. Use a 0.05 significance level to test the claim that the actual outcomes agree with the expected frequencies. Does the slot machine appear to be

24. A factory produces items from two machines: Machine A and Machine B. Machine
A produces 60% of the total items, while Machine B produces 40%. The probability
that an item produced by Machine A is defective is P(DIA)=0.03. The probability
that an item produced by Machine B is defective is P(D|B)=0.05.
(a) What is the probability that a randomly selected product be defective, P(D)?
(b) If a randomly selected item from the production line is defective, calculate the
probability that it was produced by Machine A, P(A|D).
(b) In various places in this module, data on the silver content of coins
minted in the reign of the twelfth-century Byzantine king Manuel I
Comnenus have been considered. The full dataset is in the Minitab file
coins.mwx. The dataset includes, among others, the values of the
silver content of nine coins from the first coinage (variable Coin1) and
seven from the fourth coinage (variable Coin4) which was produced a
number of years later. (For the purposes of this question, you can
ignore the variables Coin2 and Coin3.) In particular, in Activity 8 and
Exercise 2 of Computer Book B, it was argued that the silver contents
in both the first and the fourth coinages can be assumed to be normally
distributed. The question of interest is whether there were differences in
the silver content of coins minted early and late in Manuel’s reign. You
are about to investigate this question using a two-sample t-interval.
(i) Using Minitab, find either the sample standard deviations of the
two variables…
