Question 1

A random sample of 120 college seniors found that 30% of them had been offered jobs. What is the standard error of the sample proportion?
◦ 0.458
◦ 0.046
◦ 0.028
◦ 0.082
◦ 0.042

Question 2

Investigators at an agricultural research facility randomly assigned equal numbers of chickens to be housed in two rooms. In one room a group of chickens experienced normal day/night cycles, while in the other room lights were left on 24 hours a day to see if those chickens would lay more eggs. After collecting data for several days the researchers tested the hypothesis H0: μ1 - μ2 = 0 against the one-tail alternative and found P = 0.22. Which is true?
◦ There's a 22% chance that chickens housed in a lighted room produce more eggs.
◦ None of these
◦ There's a 22% chance that there's really no difference in egg production.
◦ There's a 22% chance another experiment will give these same results.
◦ The chickens in the lighted room averaged 0.22 more eggs per day
