Given the following:
Sigma =
17.8
E =
44 points
Confidence interval = 99% - 2.58
Confidence interval = 95% - 1.96
In order to get the sample size,
use the formula:
For 99% confidence level
n =
[ (z value x s) / E ]2
n =
[ (2.58 x 17.8) / 44]2
n =
1. 089 or 1 (rounded up)
For 95% confidence level
n =
[ (z value x s) / E ]2
n =
[ (1.96 x 17.8) / 44]2
n =
0.628 or 1 (rounded up)
As we decrease the confidence
level, from 99% to 95%, our confidence interval gets smaller. In additional, to
be more confident that our interval actually comprises the population mean we
have to increase the size of the interval. To ease that trade off between level
of confidence and the precision of our interval is to primarily increase the
sample size.
Answer:
Vaporware
Explanation:
Vaporware is a product, which is generally software or hardware and it is announced in the public, however, it never got released nor it got cancelled or it missed the release date by many days. Vapor is used in the name to indicate that its advertisement is full of hot air with no substance. This issue been taken care to have fair competition in the industry.
