According to a recent FCC survey, one in four cell phone users has experienced bill shock from unexpectedly high cell phone bills. A sample of 200 cell phone users was collected. Required:
a. What is the probability that more than 20% of cell phone users in the sample have experienced bill shock?
b. What is the standard error of the proportion?

answer:

step-by-step explanation:

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.

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?
