Answer:
Option B) 9.1
Step-by-step explanation:
We are given the following in the question:
Average score = 490.4
Standard deviation = 63.7
Sample size, n = 49
Formula:

Putting values, we get,
Standard error =

Thus, the correct answer is
Option B) 9.1
First ,0.75
Second, 60%
Third , 0.2
His error is the second choice.

area = (1.1 * 5.4) / 2
because triangle area = half the base times the altitude.
False, you would just divide 20 by -4 to get the answer.
