The fill weight of a certain brand of adult cereal is normally distributed with a mean of 910 grams and a standard deviation of 5 grams. We calculated the value of z for a specific box of this brand of cereal and the z value was negative. This negative z value indicates that

A. We made a mistake in our calculations, as z must always be a nonnegative number.
B. The fill weight exceeds 910 grams.
C. The fill weight is less than 910 grams.
D. The fill weight is equal to 910 grams

C. The fill weight is less than 910 grams.

Step-by-step explanation:

To normalize a given stadistical we do:

To be negative then, X should be lower than the mean.

Therefore, is the nevatige value of Z represent the value is below the mean therefore, below 910 gram

i believe the correct answer is b.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
