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
You just divide 15 by 3 and that equals 5
Answer:x-2+10=12
We move all terms to the left:
x-2+10-(12)=0
We add all the numbers together, and all the variables
x-4=0
We move all terms containing x to the left, all other terms to the right
x=4

First, add 1.4 to the number given.
-3.2 + 1.4 = 1.4 - 3.2 = -2.2
a.-2.2 is one of your answer
Next, subtract 1.4 to the number given
-3.2 - 1.4 = -4.6
a.-4.6 is your next answer
a. -2.2, a. -4.6 are your two answers
hope this helps
