Homework Help: statistics

Posted by Fafa on Thursday, May 10, 2012 at 7:39am.

On Wednesday afternoons last year a teacher regularly took her class out to study traffic flow through a small village. Her studies established that lorries pass through the village at a rate of 1.5 per 5-minute period on Wednesday afternoons.

This year she had to take her class out on Thursday morning. In a half-hour period the class observed 15 lorries passing through the village.

Stating your hypotheses clearly and using a 5% level of significance, test whether or not there is evidence that the rate of lorries passing through on Thursday mornings is greater than the rate on Wednesday afternoons
