The term statistics include various terms, including the mean, median, and mode. The mean is the summation of all the nth terms, and the median is the middle value of all the selected terms. And mode is a term that occurs most of the time in the given series.
We have to take the cumulative frequency to get the solution to some terms.
The term cumulative frequency refers to the sum of all the frequencies in a given sequence.
The term frequency refers to the times when observation will get set up.
All the set data is present in the set form concerning the gap of the same intervals. The class width is known as the difference between the upper-class limit and the lower class limit.

Question 4
Janet, Cam, and Mike arrive at a school party and there are only four cupcakes left. Everyone else has eaten enough cupcakes and will eat no more. Below is table of all possible ways these four cupcakes could be eaten by these three people. How likely it is that Janet will eat more cupcakes than Cam and Mike, given that before Janet gets to the cupcake table, Cam and Mike have already each eaten a cupcake? "Janet" "Cam" "Mike" 4 0 0 3 10 30 122 020 221 113 010 312 111 204 000 403 101 302 2
A. 4/15, because there are only four possible scenarios in which Janet eats more cupcakes out of the total 15 possibilities.
B. 3/14, since for row 1, neither Cam nor Mike has had a cupcake.
C. 1/12, because rows 1-3 don't count, as they have Mike and Cam eating only one cupcake between them (and two need to have been already eaten).
D. 1/6, since rows 1-5, 7, 8, 11, 12 aren't included as they don't have Cam and Mike as having eaten at least one cupcake each.
Question 5
A bucket was left outside several days ago, collecting water when it rained and then loosing water when it evaporated. The function W(t) gives the level of water in inches, depending on t, the number of days since it was first left outside. What does W(2) = W(5) mean?
A. The water level was only recorded on the 2nd and 5th days.
B. The water level was 5 inches on the 2nd day.
C. The water level was the same on the 2nd day as it was on the 5th day.
D. The water level was 2 inches on the 5th day.
