Answer:
So the answer for this case would be n=94 rounded up to the nearest integer
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n represent the sample size
Solution to the problem
The margin of error is given by this formula:
(a)
And on this case we have that ME =120 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The confidence2 level is 98% or 0.98 then the significance level would be
and
, the critical value for this case would be
, replacing into formula (b) we got:
So the answer for this case would be n=94 rounded up to the nearest integer
A unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 times 1012<span> km nearly 6 trillion miles.</span>
5x-14=3x
Then you just solve for x
X being 7
Hope this helped!
