This is to complex
Step-by-step explanation:
sorry for not being able to help
10/190 = 13/z...if there directly proportional, make a proportion
cross multiply
(10)(z) = (190)(13)
10z = 2470
z = 2470/10
z = 247 <==
Answer:
So the answer for this case would be n=16 rounded up to the nearest integer
Step-by-step explanation:
For this case we have the following info given:
represent the population deviation
represent the margin of error desired
The margin of error for the true mean is given by this formula:
(a)
And on this case we have that ME =0.03 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The confidence level is 80%, the significance would be and the critical value for this case is , replacing into formula (b) we got:
So the answer for this case would be n=16 rounded up to the nearest integer
Answer:C
Step-by-step explanation:
Answer:
The answer is 425
Step-by-step explanation:
Place value would be...
400
