Z value is a numerical measurement that describe a value relationship to the mean of a group of values. The standard deviations is 1.25 above the mean is 14,500 hours.
<h3>Given information-</h3>The mean for the bulb is 12,000 hours.
The standard deviation for the bulb is 2000 hours.
Sample value is 14500.
To find out the how many standard deviation is 14500 mean away from the mean the z value of the mean should be calculated.
<h3>Z value</h3>Z value is a numerical measurement that describe a value relationship to the mean of a group of values. Z value is the ratio of the difference of the sample value and mean
to the standard deviation. Thus the z value for the given mean
is,
Thus the standard deviations is 1.25 above the mean is 14,500 hours.

Answer:
a. $240.03
b. $43,205.04
c. Principal = 46.29%
Interest = 53.71%
Step-by-step explanation:
The computation is shown below:
a. For computing the monthly payment we need to apply the PMT formula i.e to be shown in the attachment below
Given that,
Present value = $25,000
Future value or Face value = 0
RATE = 12% ÷ 12 months = 1%
NPER = 15 years × 12 months = 180 months
The formula is shown below:
= PMT(RATE;NPER;-PV;FV;type)
The present value come in negative
So, after applying the above formula the monthly payment is $240.03
b. Now the total amount paid is
= Monthly payment × time period
= $240.03 × 180 months
= $43,205.04
c. Now the percentage is
For principal
= $25,000 ÷ $43,205.04 × 100
= 46.29%
And, for the interest, it is
= 100% - 46.29%
= 53.71%
