Answer:
It is provided that 10% of the men aged 55 to 64 have cholesterol level <u>270 mg/dl</u> or higher.
Step-by-step explanation:
Let <em>X</em> = blood cholesterol levels of men aged 55 to 64 years.
The random variable <em>X</em> follows a Normal distribution with mean <em>μ</em> = 222 mg/dl and standard deviation <em>σ</em> = 37 mg/dl.
It is provided that 10% of the men aged 55 to 64 have cholesterol level <em>x</em> mg/dl or higher.
Compute the value of <em>x</em> as follows:
Use the <em>z</em>-table to compute the value <em>z</em> for the probability 0.90.
The value of <em>z</em> is 1.29.
Compute the value of <em>x</em> as follows:
Thus, 10% of the men aged 55 to 64 have cholesterol level 270 mg/dl or higher.
