About 76% of college professors said that if they could pick a career over again, they would choose to be a professor again. A random sample of 59 college professors in Colorado showed that 47 claim they would choose college teaching again. Does this indicate the proportion of professors in Colorado who would choose the career again is greater than the national rate of 76%? Use a α = 0.01 level of significance. Hypotheses: Significance Level: Calculate: • Sample Statistic: • Sample Standard Deviation: • Test Statistic: • P-Value: Conclusions:
