requirement.

Answer 1

Answer: B) The report accurately stated the results because the sample size was sufficient.

Explanation:

The given statement in the report about a possible causal relationship between age and responses cannot be determined solely based on the information provided. However, the statement can be considered accurate because the sample size of 100 people from a local high school was sufficient to provide reliable results. The fact that the majority of those surveyed were teenagers does not make the report inaccurate or unreliable. The mean response score of 1.5 and the standard deviation of 0.3 are valid indicators of the attitudes of the surveyed group towards the age at which an individual can receive a driver's license.
