Dataset for question (4.2.) Amount of Money Spent on Vehicle extras by 7 customers: Customer Amount_Spent х1 2300 x2 2386 x3 1920 х4 1578 x5 3065 х6 2312 x7 1790 4.2. A car dealer wants to know if the purchasing habits of buyers buying extras for their vehicles have changed. He is particularly interested in determining if male buyers are willing to spend more money on extras for their cars. Based on data collected over the past year, he has estimated that the distribution of the amount of money spent on extras is approximately normally distributed with an average of R2 000 per customer. To test this hypothesis, he has collected the following information concerning the amount of money that the last seven male customers have spent on extras (Rands). Provide all the steps.

(a) Suppose we toss one biased coin with probability of heads p € (0, 1). Let X = 1 if the coin turns up heads, X = 0 if the coin lands tails. What is E[X]? What about Var[X]? X is said to be a Bernoulli random variable with probability of success p. We write X~ Ber(p). (b) Now, suppose we toss n independent coins, each of which has probability p of turning up heads. Let N denote the number of heads out of the n tosses. What is P(N = k), for k = 0, 1,..., n? What is E[N]? What about Var [N]? (Hint: these last two points can be solved easily with the previous question). Such a random variable is said to be Binomially distributed with n trials and probability of success p. We write X Bin(n, p) correspondingly. (c) Instead of tossing a fixed number of coins, you now toss independent coins until you see the first heads, where p is still the probability that any given coin lands heads up. Let N represent this number of tosses. What is P(N = n) for n € N? Likewise, what is E[N]? Var[N]? The…
