Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:

In which:
is the sample mean.
- s is the standard deviation for the sample.
The critical value, using a t-distribution calculator, for a two-tailed <em>95% confidence interval</em>, with 49 - 1 = <em>48 df</em>, is t = 2.0106.
Hence:


The 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).

Determining if you meet the requirements to dual-enroll or take college classes.
An outcome that would demonstrate that a given population has evolved can be the presence of an adaptation.
<h3>What is an adaptation?</h3>
An adaptation is any morphological and/or phenotypic feature aimed at challenging environmental conditions.
Adaptations are, for example, aerodynamic wings in insects that allow them to survive in the low atmosphere.
In conclusion, an outcome that would demonstrate that a given population has evolved can be the presence of an adaptation.
