Use the given information to find the minimum sample size required to estimate an unknown population mean.
margin of error: $120, confidence level: 95%, standard deviation=$593
a)83
b)66
c)94
d)133

C) 94

Step-by-step explanation:

Margin of error = critical value × standard error

ME = CV × SE

Assuming n > 30, we can approximate CV with a normal distribution.  At P = 95%, CV = 1.96.

SE = σ / √n

SE = 593 / √n

Therefore:

120 = 1.96 × 593 / √n

n = 94

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
