Answer:

Step-by-step explanation:

SD of mean = 2.3/ $\sqrt{55}$ = 0.418

5 hours = 300 minutes

300 minutes/55 students = 5.45 min/student

The problem asks what is the probability he needs more than an average of 5 min/student

P(XBAR < 5.0) = P((XBAR - 4.8) / 0.418) < (5.0 - 4.8) /0.418) = P(Z < 0.478) = 0.8893

P(XBAR > 5.0) = 1 - 0.8893 = 0.1107
