Answer:

100

90+100+99+91 = 380

after that divide the answer (380) by 4 and you get 95.

The reason why you divide by 4 is because there was four numbers that you had to sum up to get 380.

The answer is 100 if you round up!

Answer:

Step-by-step explanation:

To find the average you would add all the scores up and divide by the number of scores you have, so you would do 90+100+99+91 and get 380. Then divide by 4 to get 95.

g Z-Test for Population Means Calculate z-statistic of a population mean. Keith sampled 10 private universities in Colorado and

scoray [572]

Answer: 2.46

Step-by-step explanation:

Formula for x-score is given by :-

$Z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

, where $\overline{x}$ = Sample mean , $\mu$ = population mean, $\sigma$ = population standard deviation, n= sample size.

As per given , n=10

$\mu$ = $29,056

$\sigma$ = $3,339

$\overline{x}$ = $31,650

Then,

$z=\dfrac{ 31650-29056}{\dfrac{3339}{\sqrt{10}}}\\\\=\dfrac{2594}{\dfrac{3339}{3.16227766017}}\\\\=\dfrac{2594}{1055.88451073}=2.45670807142\approx 2.46$

Hence, the z-score = 2.46
