Answer:
So the answer for this case would be n=2663 rounded up to the nearest integer
Step-by-step explanation:
We have the following info:
margin of error desired
the standard deviation for this case
The margin of error is given by this formula:
(a)
And on this case we have that ME =50 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The critical value for 99% of confidence interval now can be founded using the normal distribution. The significance is . And for this case would be
, replacing into formula (b) we got:
So the answer for this case would be n=2663 rounded up to the nearest integer
Greetings!
To find the percent of a number, you mutliply the percent by the number, then divide by 100. We can use this rule to create an equation:
Multiply both sides by 100.
Simplify.
Divide both sides by 50.
Simplify.
36% of 50 is 18.
Hope this helps.
