The set of numbers 
belongs to is termed as B. irrational numbers.
There are two main types of numbers, real and imaginary. Real numbers are also subdivided into rational and irrational numbers. Irrational numbers are numbers that cannot be written in a fractional form which is the opposite of rational numbers. These can either be non-terminating or repeating. An example of a non-terminating irrational number is the value of pi (3.1415...) and an example of a repeating irrational number is 15.55555...

Answer:
0.8770
Step-by-step explanation:
We are dealing with a mean of a sample, so we use the formula
Our mean, μ, is 174.9 and our standard deviation, σ, is 35.2. Our sample size, n, is 35. To find P(X > 168),
z = (168-174.9)/(35.2÷√35) = -6.9/(35.2÷5.9161) = -6.9/5.9499 = -1.16
Using a z table, we see that the area under the curve to the left of this value is 0.1230. However, we want the area to the right; this means we subtract from 1:
1-0.1230 = 0.8770
