Answer:
Option C. No, because the two populations from which the samples are selected do not appear to have equal variances.
Step-by-step explanation:
The variance measures how far a set of (random) numbers are spread out from their average value.
The fact that the younger adults show diversity in their brain activity while the older adults produce similar activities show that there are no equal variances in the two populations from which the samples are selected.
Therefore it would not be valid for Dr. Park to use the independent-measures t-test to test whether the brain activity of younger adults is different from that of older adults during a visual recognition task

In around 6.35 years, the population will be 1 million.
<h3> how many years will it take for the population to reach one million?</h3>
The population is modeled by the exponential equation:

Then we just need to solve the equation for t:

Let's solve that:

If we apply the natural logarithm to both sides:

So in around 6.35 years, the population will be 1 million.
