Answer:
Number 8 the answer is 120
Number 10 answer is 115
Step-by-step explanation:
8. 180-60=120
it's because the straight line is 180 then you just need to solve it use this
10. 180-65=115
the reason same like number 8
Hope this answer can help you to solve the math problems
You basically just need to multiply 26.2 by 6.2

Answer:
The 90% confidence interval is 0.575 to 0.625.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence interval
, we have the following confidence interval of proportions.

In which
Z is the zscore that has a pvalue of
.
For this problem, we have that:

90% confidence interval
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 90% confidence interval is 0.575 to 0.625.
