Hi Strawberry12,

For problem 5, what you want to do is simplify the expression, cross multiply, then solve for e:

2(2/3)e = 1/18
(8/3)e = 1/18
8e/3 = 1/18
(8e x 18) = (3 x 1)
144e = 3
e = 3/144
e = 1/48

You would do the same thing for problem 6:

-1(2/7)m = 6
-(9/7)m = 6
-9m / 7 = 6 / 1
-9m = 7 x 6
-9m = 42
m = 42 / -9
m = -14/3

Hope this helps!

Good luck.

Using the z-distribution, it is found that the 90% confidence interval is given by: (0.6350, 0.6984).

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which:

  • \pi is the sample proportion.
  • z is the critical value.
  • n is the sample size.

In this problem, we have a 90% confidence level, hence\alpha = 0.9, z is the value of Z that has a p-value of \frac{1+0.9}{2} = 0.95, so the critical value is z = 1.645.

The sample size and the estimate are given by:

n = 600, \pi = \frac{400}{600} = 0.6667

Hence, the bounds of the interval are given by:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6667 - 1.645\sqrt{\frac{0.6667(0.3333)}{600}} = 0.6350

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6667 + 1.645\sqrt{\frac{0.6667(0.3333)}{600}} = 0.6984

The 90% confidence interval is given by: (0.6350, 0.6984).
