Question

A school reports that 80% of its graduates get jobs within one year. You take a random sample of 68 graduates, of whom 50 got a job within one year. Is this enough evidence to show that a significantly different percent of graduates get jobs than advertised by the school? (Use αα=0.01)

For this study, we should use

The null and alternative hypotheses would be:
  H0H0:           (please enter a decimal)
  H1H1:           (Please enter a decimal)

The test statistic = (please show your answer to 3 decimal places.)

The p-value = (Please show your answer to 4 decimal places.)

The p-value is αα

Based on this, we should the null hypothesis.

As such, the final conclusion is that ...
- The sample data suggest that the populaton proportion is significantly different than 80% at αα = 0.01, so there is sufficient evidence to conclude that the percent of graduates get jobs within one year is different than 80%
- The sample data suggest that the population proportion is not significantly different than 80% at αα = 0.01, so there is not sufficient evidence to conclude that the percent of graduates get jobs within one year is different than 80%.
