Answer: 5.475 x 10^8
Step-by-step explanation: The number has to be in between 1 and 10 so you move your decimal as many times as you need to. In this situation it is 8, so that is your power
Answer:
Step-by-step explanation:
Confidence intervals are constructed to estimate an unknown parameter of the population. This is usually population mean and sometimes, population standard deviation.
Since we are dealing with proportion, then the sample proportion would be used to determine the population proportion
Therefore, the pieces of information that the surveyor requires in order to construct the confidence interval are
a. the exact size of the sample that is surveyed
b. the proportion of people in the sample with the characteristic
d. the level of confidence desired
In order to solve, the sample, p proportion is determined.
p = number if people in the sample with the characteristic/ number of sample
q = 1 - p
Margin of error = z × √pq/n
Confidence interval = p ± margin of error
