Answer:
The sample size needed is 2401.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error of the interval is:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
Estimate the sample size needed if no estimate of p is available so that the confidence interval will have a margin of error of 0.02.
We have to find n, for which M = 0.02.
There is no estimate of p available, so we use
The sample size needed is 2401.
To find the decimal form a percent, divide by 100.
590% = 5.9
Turn into fraction.
590% = 59/10 or 5.9/1
Hope This Helped! Good Luck!
Answer:
B. There is no solution to the equation.
Step-by-step explanation:
Every step in the solution is correct.
Since the last line is a false statement, 5 = 1, that means there is no solution.
Answer: B. There is no solution to the equation.
One correct answer would be 4 rows of 8 stamps each.
It sounds like you're doing arrays. If you weren't given any options to choose from and you have to create this yourself, then you can use the answer I helped you with.
With arrays there are different examples you can create. The only rule you have to follow is that you have everything shared equally with each row, meaning each row of what you choose can have no more and no less than any other row.
Ex: (given above) 2 rows of 16
4 rows of 8
8 rows of 4
16 rows of 2
The answer is 6.625. :D .
