Answer:
And the margin of error with this one:
Step-by-step explanation:
Assuming that the parameter of interest is the sample mean . And we can estimate this parameter with a confidence interval given by this formula:
(1)
For this case the confidence interval is given by (1.9, 3.3)
Since the confidence interval is symmetrical we can estimate the sample mean with this formula:
And the margin of error with this one:
The compounding equation is
. So
Divide by 3725
Daily =
=
= 1.6225
Monthly =
=
= 1.6218
Quarter =
=
= 1.6204
Yearly =
=
= 1.6141
The answer is yearly.
m<CAE = 90: definition of perpendicular
p.s. ty for this!
