Data from the Motor Vehicle Department indicate that 80% of all licensed drivers are older than age 25. In a sample of n = 50 people who recently received speeding tickets, 33 were older than 25 years and the other 17 were 25 or younger. Is the age distribution for this sample significantly different from the distribution for the population of licensed drivers? Use α = .05

Identify the proposed analysis.
State your scales of measurement (e.g. nominal) for variables that will be used in the analysis.
State the null and alternative hypotheses.
State the test assumptions and make a decision.
State the inferential statistic and p-value.
Make a decision. Based on your decision, identify and explain the type of error you could be making.

Data from the Motor Vehicle Department indicate that 80% of all licensed drivers are older than age 25. Information on the age of n = 50 people who recently received speeding tickets was sourced by researchers who are interested in whether the age distribution for the sample of drivers who recently received speeding tickets is different from the age distribution for the population of licensed drivers. State your proposed analysis and why you chose that analysis. State the scales of...
