Answer:
The lowest 5% of data ends at 57.73.
Step-by-step explanation:
Let the random variable <em>X</em> follow a Normal distribution with mean μ = 80.6 and standard deviation σ = 13.9.
The lowest 5% of the distribution can be expressed in terms of probability as follows:
Compute the value of <em>x</em> as follows:
The <em>z</em> score such that P (Z < z) = 0.05 is <em>z</em> = -1.645.
**Use the <em>z-</em>table for the for the <em>z</em>-score.
The value of <em>x</em> is:
Thus, the lowest 5% of data ends at 57.73.

Answer:
0.098
Step-by-step explanation:
Given that when filling out the 2000 Census, people could choose one of four options to describe their marital status.
Data from the 2000 Census were used to compute the following probabilities
Marital status Never married Married widowed Divorced total
Prob 0.239 0.595 0.068 0.098 1
Actually we were not given probability for divorced but using total probability =1 we arrived at the probability for divorced as
1-sum of the remaining probabilities
=
the probability that a randomly selected U.S. adult is divorced
= 0.098
