this answer is the anser if you are dividing log 10 and 27 1/3 by log 10 81
Answer:
And replacing the info from the problem we have:
So then the best estimator for the true proportion p is given by or equivalent to 3.2 %
Step-by-step explanation:
We want to find a confidence interval for a proportion p who represent the parameter of interest.
The confidence interval would be given by this formula:
For this case the 90% confidence interval is given by (1.8%=0.018, 4.6%=0.046) after apply the last formula
Since the confidence interval is symmetrical we can estimate the point estimator of the true percentage with this formula:
And replacing the info from the problem we have:
So then the best estimator for the true proportion p is given by or equivalent to 3.2 %
Answer:
x=10
Step-by-step explanation:
By the Trapezoid Midsegment Theorem, the midsegment of a Trapezoid is 1/2(the sum of the 2 bases.
4x-20=1/2(23+17)
4x-20=1/2(40)
4x-20=20
4x=40
x=10
0.72 because when you divide 2.16 by 3 you will get 0.72
