Step-by-step explanation:
Using product and quotient property:
log x + log y can be displayed as log xy
Because we're subtracting 2 log z we can use the power property to rewrite this as log z^2
Now, using quotient property we can display this expression as:
<h3>log xy/z^2</h3>
Answer:
90% confidence interval: (70.41,86.89)
Step-by-step explanation:
We are given the following in the question:
Point estimate = 78.65
Margin of error, E = 8.24
Confidence level = 90%
Significance level = 10%
Formula:
Putting the values, we get,
(70.41,86.89) is the required 90% confidence interval.
