Question

A firm uses trend production and seasonal Factors to simulate cells for a given time period. It’s assigns “0” if sales fall, “1” if sales are steady, “2” if sales rise moderately, and “3” if sales rise a lot. The simulator generates the following output.

0 1 1 2 2 0 1 1 2 3 2 1 2 1 2 2 1 2 3 2 2 2 0 3 1 0 2 1 2 1

Estimate the probability that sales will rise at least moderately.

A. 0.452
B. 0.613
C. 0.516
D. 0.512

Answer 1

At least moderately means that it will also include "sales rise a lot" So the probability is

=16/30

=8/15
