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.
