the ress m 5. Data from the Motor Vehicle Department indicate that 80% of all licensed drivers are older than age 25. A) In a sample of n 50 people who recently received speeding tickets, 33 were older than 25 years and the other 17 were age 25 or younger. Is the age distribution for this sample significantly different from the distribution for the population of licensed drivers? Use a = .05. 1. State the alternative hypothesis and null hypothesis 2. Calculate the degrees of freedom (df) for chi-square. 3. Using an a = .05, what is the critical value for chi-square (xcrit)? 4. Calculate chi-square (x) and provide a statement with words about your decision 5. Write a sentence demonstrating how the results from the hypothesis test would appear in a research report.
