Geoff has been running a restaurant in the city for many years. He knows from experience that the proportion of customers that leave tips at this restaurant is 0.58. Geoff has recently opened a restaurant in a suburban area. It seems that tipping habits are different in the suburbs: Geoff believes that the proportion of customers that tip at his new restaurant (p) may be different to 0.58. He conducts a hypothesis test to find out. The null and alternative hypotheses are:H0: p = 0.58Ha: p ≠ 0.58Geoff takes a random sample of 117 customers and notes whether or not they leave a tip. In this sample, the proportion of people that leave a tip is 0.62.a)Calculate the test statistic (z). Give your answer to 2 decimal places.
