Explanation:
Answer:
a) We need to find p(x<68.15)
Standardize x to z, we have, z = (68.15-μ)/σ
=(68.15-57)/8.1
=1.38
Reading from standard normal tables,
p(z<1.38) =0.9162.
b) We need to find p(x>54.4)
Standardize x to z, we have, z = (54.4-μ)/σ
=(54.4-57)/8.1
=-0.32
Reading from standard normal tables,
p(z>-0.32) = 0.6255

In math equations and inequalities, they are said to be both mathematical sentences that is created to link two expressions such as the use of symbol >, <, ≤ or ≥. when two items are in a state of inequality.
<h3>What is equation and inequality?</h3>
An equation is known to be a type of mathematical statement that depicts the equal state of two expressions. It is often depicted with the symbol = which shows equality.
While an inequality is known to be a mathematical statement that shows that two given expression is said to lesser than or more than one another.
