The heights of male students are normally distributed with a mean of 160 cm and a standard deviation

kompoz [17]

Answer:

2.28%

Step-by-step explanation:

As this is normally distributed, we can use z scores to find the percentage.

First, find the z-score for 148.

The z-score that you get is:

(148-160)/2=2

As we see that z=2, we can use a calculator or a z-score chart to find the percentage less than a z score of 2.

I used my chart and found: 2.28%

Answer:

The approximate value of the investment in one year is 4183.

Step-by-step explanation:

The formula for finding the compound interest for one year that compounded quarterly is :

$A = P(1 + \frac{r}{400} )^{4t}$

Here,

P - Principal = 4000

r - 4.5%

t - 1

Therefore,

$A = 4000(1 + \frac{4.5}{400} )^{4}$

$= 4000(1.01125)^{4}$

$= 4000(1.04577)$

= 4183.08

Hence, the approximate value of the investment in one year is 4183.
