Did your interval capture the 2014 employment rate of 84.5%? Does the interval cause you to question whether the population proportion for recent petroleum engineering graduates’ employment is less than 84.5%? Why or why not? Recall your decision for the significance test you conducted and that you recorded in #4. How does the decision compare with the conclusion you drew from the confidence interval? Did your conjecture for the relationship between significance tests and confidence intervals hold? If not, make a new conjecture.
