Answer:

approximately 2 weeks

Explanation:

Assuming normal distribution, we have

mean m = 30.8

standard deviation s = 2.6

The standard random variable is given by Z = (x - 30.8)/2.6

where x denotes the number of cases lost

we are to evaluate probability of losing more than 36 i.e P(x > 36)

This will be P(Z > (36 - 30.8)/2.6) = P(Z > 2)

using the z-score table, we have this probability to be 0.0228

so the number of weeks is given by 52*0.228 = 1.19

which is approximately 2

A value two standards deviation from the mean is more likely to occur than a value three standard deviations from the mean.
Norma-Jean [14]
This is True - A.

This is true because values which are less far apart from the mean; two standards deviations being closer than three standard deviations from the mean, are also more likely to occur. This is best illustrated when viewing a Gauss curve or a normal bell curve.
