Certain kinds of tumors tend to recur. The following data represent the lengths of time, in months, for a tumor to recur after chemotherapy.

For this problem, use five classes.
a. Find the class width.
b. Make a frequency table showing class limits, class boundaries, midpoints, frequencies, relative frequencies, and cumulative frequencies.

d. It is the same distance from zero as the number she tells you

Step-by-step explanation:

Case 1: Let Shanika thought a positive rational number

Let the number that Shanika thought be c.

Then, the distance of it from zero = |c - 0| = c.

But, the number she told = -c

The distance of -c from zero = |0--(-c)| = c

Case 2: Let Shanika thought a negative rational number

Let the number that Shanika thought be -c (c > 0).

Then, the distance of it from zero = |0--(-c)| = c.

But, the number she told = c

The distance of -c from zero = |c - 0| = c

In both cases, the number she thought is the same distance from zero as the number she tells us
