Answer:
The percent equation states that the part equals the percent multiplied by the whole number.
Considering that we have the standard deviation for the sample, the t-distribution will be used, and the critical value is t = 2.6682.
<h3>When should the t-distribution and the z-distribution be used?</h3>
- If we have the standard deviation for the sample, the t-distribution should be used.
- If we have the standard deviation for the population, the z-distribution should be used.
In this problem, σ is not known, hence we get the standard deviation of the sample from the histogram and the t-distribution is used.
Using a t-distribution calculator, considering a <em>confidence level of 99%</em> and 56 - 1 = <em>55 df</em>, the critical value is t = 2.6682.

Information centers are situated in the middle to draw attention of knowledge seekers and to capture intellectual outputs.
<h3>What is an information center?</h3>
An information center is a center or place designed specifically for storing, processing, and retrieving information for dissemination or dispersion at regular intervals, on demand according to needs of users.
The varied forms of information centers are:
- Information Analysis centers
- Clearing houses
- Data centers
- Data banks
Information centers are built in the center of communities in order to;
- Draw attention to knowledge seekers
- Capturing and preserving the intellectual output of an organization
