To solve, just invert the equation so 27.75+x=30 becomes x=30-27.75=2.25, making your answer $2.25.
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.
Step-by-step explanation:
a^2 + 8^2 = 10^2
a^2 =10^2 - 8^2
a^2 =100-64
a^2 =36
(square root it)
a =6
