Tasks that require you to compare, contrast, or evaluate are using the ________ intelligence component of the triarchic theory of intelligence.

 

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.
