Answer:

-1 = x

Step-by-step explanation:

Distribute 2 into x - 10 first to get to this equation which is -22 = 2x - 20.  Add 20 on both sides to get -2 on the left side.  Divide 2 on both sides to get your x-value which is -1.

Starting salaries of 90 college graduates who have taken a statistics course have a mean of $43,993 and a standard deviation of
inysia [295]

Answer:

a) E = 2482.90

b) 99% Confidence interval: (41510.1,46475.9)

Step-by-step explanation:

We are given the following in the question:

Sample mean, \bar{x} =$43,993

Sample size, n = 90

Alpha, α = 0.051

Sample standard deviation, s = $9,144

a) The margin of error

Formula:

z_{critical}\text{ at}~\alpha_{0.01} = 2.576

E =z_{critical}\times \displaystyle\frac{s}{\sqrt{n}}\\\\E = 2.576\times \frac{9144}{\sqrt{90}}\\\\E = 2482.90

b) 99% Confidence interval:  

\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

43993 \pm 2482.90 = (41510.1,46475.9)
