Question

The average age for licensed drivers in the country is µ = 42.6 with a standard deviation of a 12. The distribution of ages is approximately normal. A researcher obtain a sample of n = 36 drivers who received parking tickets.The average age for these drivers was M40.7. Is this a reasonable outcome.for a sample of n = 36 or is this sample mean an extreme value (provide analyses for your decision). bThe same researcher also obtained a sample of n = 16 drivers who received speeding tickets. The average age for this sample was 34.4. Is this a reasonable outcome for a sample of n = 16, or is the sample mean very different than what would usually be expected? (Again, provide the analyses for your decision).
