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
1 km = 0.62 mi
1 mi = 1.6 km
80*0.62
-or-
60*1.6
