A gambler plays a simple card game in which a card is drawn from a shuffled deck and the suit isrecorded. After each repetition, the card is returned to the deck and the deck is re-shuffled, so thatthe probability of a given suit in a fair deck is always 0.25. But after 160 repetitions, the followingdistribution of suits occurs:heartsdiamondsspadesclubs29455234At the 5% significance level, is there sufficient evidence that the game is not fair? State andperform the appropriate goodness-of-fit test. Your answer must include the following, as usual:a) a statement of the hypothesesb) The critical value of the test.c) The value of the test statistic, andd) a statement of conclusion.

a) It is needed to test whether the game is not fair.

(This is a introduction to statistics course) From past records, a department store finds that 70% of the people who enter the store will make a purchase on Black Friday. Suppose that 3 customers are randomly selected at the store, answer the following questions: 1) What is the chance that exactly one out of three customers make a purchase? Give your answer (%) rounded to one decimal place. (For example, if your answer is 0.5125 (51.25%), then it will be 51.3% after being rounded to one decimal place.) 2) Explain clearly.
