# A task force is studying the need for an additional bicycle path on a large university campus.

A task force is studying the need for an additional bicycle path on a large university campus. It is assumed that the distribution of bicyclists using a path between classes is normally distributed with a population variance of about 64. A random sample of 7 existing bicycle paths showed that the sample mean number of bicyclists using a path between classes was 33.

A group of interested students took its own sample of 5 different bicycle paths, and computed a confidence interval for the population mean that ranged from (16.0 , 25.173 ). What is the probability content (or the level of confidence) of this interval?
