t he number of views expected to be four weeks from now can
be calculated using the equation:
F = P ( 1+i)^n
Where F is the future views
P is the present views
i is the percent increase in views
n is the number of weeks
F = 15 ( 1+ 0.22)^4
F = 33 views
Answer:
So the answer for this case would be n=22547 rounded up to the nearest integer
Step-by-step explanation:
Let's define some notation
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n represent the sample size
represent the margin of error desire
The margin of error is given by this formula:
(a)
And on this case we have that ME =+1 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 would be
and the critical value
, replacing into formula (b) we got:
So the answer for this case would be n=22547 rounded up to the nearest integer
Step-by-step explanation:
A is 16.9%
B is 352,181
