Suppose that a group of high school English teachers surveyed all incoming freshman about their reading habits and found that 51.5% read for pleasure at least once a week. To test if the reading habits of seniors were different from the freshmen, they surveyed a random sample of 70 seniors and found that 27 of them read for pleasure at least once a week. The teachers want to use a one-sample z-test for a population proportion with a significance level of α=0.10 to see if the proportion of seniors who read for pleasure at least once a week, p, is different from the proportion of freshmen who read for pleasure at least once a week. Have the requirements for a one-sample z-test for a proportion been met? If not, leave the remaining questions blank. a. Yes, because the sample is random, the setting is binomial, and the sample includes at least 10 successes and at least 10 failures. b. No, because there are two samples: the freshman and the seniors, both of whom are surveyed about their reading habits. c. Yes, because the sample is random, the setting is binomial, and the sample size is at least 30. d. No, because the population standard deviation is unknown.
