Answer:
A
Step-by-step explanation:
We know that in normal distribution, approximately 34% of bags will fall with in one standard deviation on one side. On both sides within the range of 1 standard deviation, 34 + 34 = 68 % of bags will fall.
Our range is:
1600 to 1620
1610 - 10 to 1610 + 10
So the answer is 1
That means, that 68% is the answer.

Step-by-step explanation:
Radio(x) weeks P(x)
0 5 5/100 = 0.05
1 27 27/100=0.27
2 27 27/100 = 0.27
3 27 27/100 = 0.27
4 9 9/100=0.09
5 5 5/100=0.05
We know that
Mean ,μ
μ = 0 x 0.05 + 1 x 0.27 + 2 x 0.27 + 3 x 0.27 + 4 x 0 .09 + 5 x 0.05
μ =2.23
