The stock price of a particular asset has a mean and standard deviation of $58.50 and $8.25, respectively. Compute the 95th percentile of this stock price.

a. $22.76
b. 1.645
c. $44.93
d. $72.07

d. $72.07

Step-by-step explanation:

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

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

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:

Compute the 95th percentile of this stock price.

This is X when Z has a pvalue of 0.95. So it is X when Z = 1.645.

So the correct answer is:

d. $72.07

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
