Answer:

Statistics and Probability

Step-by-step explanation

PROBLEM 1

The excel function is used to compute the variance of a sample of bag weights (lbs) is ?VAR.S?

PROBLEM 2.

Total of 4, 6, and 9 are 12 out of 36 outcomes. Basically, the number of results not 4, 6, and 9 is 24.

So, the probability that the sum is none of 5, 6, and 9 is ?p=24/36??

PROBLEM 3

The number of production that does not meet the acceptable limits is based from the data.
