1. a) Human gestation times (pregnancies) have a mean of
about 266 days, with a standard deviation of about 10
days. If we record the gestation times of a sample of
100 women, do we know that a histogram of the times
will be well modeled by a Normal model?

the answer is a if my teacher taught me correct

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

step-by-step explanation:

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
