2n+5=20

Subtract 5 from 5 and 20

2n=15

Divide 15 and 2 by 2

n=7.5

n ≈ 7.5

2n + 5 ≈ 20

5 - 20 = 2n ≈ 15

Subtract 5 from 5 and 20 .

2n = 15

15 ÷ 2 ≈ 7.5

n ≈ 7.5

In a normal distribution, what is the probability that a data value will fall below the

Serga [27]

Answer:

A 99.96%

Step-by-step explanation:

The z score shows by how many standard deviations the raw score is above or below the mean. The z score is positive if the raw score is above the mean while the z score is negative if the raw score is below the mean. The z score is given by:

$z=\frac{x-\mu}{\sigma} \\\\where\ z=z-score,\ x=raw\ score,\mu=mean, \ \sigma=standard\ deviation\\\\For\ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }$

The probability can be gotten from the normal distribution table. Therefore from the normal table:

P(z < 3.37) = 0.9996 = 99.96%
