D.The answer should be about $10,000.The students answer is not correct.
The proportion of employees in entry-level positions at the company who earn at least $ 42,000 will be 0.48466.
<h3>What is a normal distribution?</h3>
The Gaussian distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
According to a recent survey, the salaries of entry-level positions at a large company have a mean of $ 41,750 and a standard deviation of $ 6500.
Assuming that the salaries of these entry-level positions are normally distributed.
Then the proportion of employees in entry-level positions at the company who earn at least $ 42,000 will be
The z-score is given as
z = (x - μ) / σ
Then we have
z = (42000 - 41750) / 6500
z = 0.03846
Then we have
P(x ≥ 42000) = P(z ≥ 0.03846)
P(x ≥ 42000) = 1 - P(z < 0.03846)
P(x ≥ 42000) = 1 - 0.51534
P(x ≥ 42000) = 0.48466
