The starting salaries of individuals with an MBA degree are normally distributed with a mean of $40,000 and a standard deviation

liraira [26]

Answer:

d. 76.98%

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 40000, \sigma = 5000$

What percentage of MBA's will have starting salaries of $34,000 to $46,000?

This is the pvalue of Z when X = 46000 subtracted by the pvalue of Z when X = 34000. So

X = 46000

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{46000 - 40000}{5000}$

$Z = 1.2$

$Z = 1.2$ has a pvalue of 0.8849

X = 34000

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{34000 - 40000}{5000}$

$Z = -1.2$

$Z = -1.2$ has a pvalue of 0.1151

0.8849 - 0.1151 = 0.7698

So the correct answer is:

d. 76.98%

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

From given picture we can see that X is mid point of line PQ

So PQ=2PX

From given picture we can see that Y is mid point of line PR

So PR=2PY

Now consider triangles PRQ and PYX

Sides PQ and PX has same ratio as of sides PR and PY (as calculated above)

angle XPY= angle QPR (common angle)

Hence triangles PRQ and PYX are similar.

We know that ratio of the sides of similar triangles is always equal so we can write:

$\frac{PQ}{PX} = \frac{QR}{XY}$

Plug the given values QR=8 and PQ=2PX

$\frac{2PX}{PX} = \frac{8}{XY}$

$\frac{2}{1} = \frac{8}{XY}$

$2 = \frac{8}{XY}$

$XY = \frac{8}{2}$

$XY = 4$

Hence final answer is XY = 4 units.
