Answer:
So the answer for this case would be n=183 rounded up to the nearest integer
Step-by-step explanation:
Information provided
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n represent the sample size
the margin of error desired
Solution to the problem
The margin of error is given by this formula:
(a)
And on this case we have that ME =0.023 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 97% or 0.97 and the significance would be and
then the critical value would be:
, replacing into formula (5) we got:
So the answer for this case would be n=183 rounded up to the nearest integer
Answer:
I only
Step-by-step explanation:
given h = - at² + bt + c
the vertex = -
Thus altering a or b effects the position of the vertex
and the maximum value is the value of the vertex
Altering c effects the h-intercept only
