~4~ 14) Professor What-A-Guy surveyed a random sample of 360 statistics students. One of the questions was "Will you take another mathematics class?" The results showed that 220 of the students said yes. What is the sample proportion, p, of students who say they will take another math class? 15) A national caterer determined that 37% of the people who sampled their food said that it was delicious. A random sample of 144 people is obtained from a population of 5000. The 144 people are asked to sample the caterer's food. If p is the sample proportion saying that the food is delicious, what is the standard deviation of the sampling distribution of p? 16) The National Association of Realtors estimates that 23% of all homes purchased in 2004 were considered investment properties. If a sample of 500 homes sold in 2004 is obtained what is the probability that at least 150 homes are going to be used as investment property? ~4~ 14) Professor What-A-Guy surveyed a random sample of 360 statistics students.
