One question on the survey is: would you recommend your realtor to a friend? Our realtor, whose name is Sara, had a friendly competition going with a fellow realtor, Brandon, about this question. They decided to settle it with some statistics! In a random sample of 75 of Sara's clients, 63 answered "Yes." In a random sample of 82 of Brandon's clients, 59 answered "Yes." At the a = 0.10 significance level, perform a hypothesis test to determine whether the population proportions of clients who would recommend them are different for Sara and Brandon. Use Sara's customers as population 1. What is the sample proportion of Sara's clients who said they would recommend her?
