Is the normal distribution curve is also called the bell curve? true or false

True.

Step-by-step explanation:

In statistics, the normal distribution curve shows how many times an experiment will produce a certain result. The curve is symmetrical and bell shaped, showing that trials will commonly give a result near the average, but will sometimes diverge by large amounts.

This bell shaped line formed in the graphical representation of normal distribution, this fact gives the term "bell curve".

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
