Answer:

<em>B)</em><em> 8.9 lbs </em>

<em>C)</em><em> 9.5 lbs </em>

<em>D)</em><em> 9.8 lbs </em>

<em>E)</em><em> 10.4 lbs</em>

Step-by-step explanation:

From the graph, 9.5 is the mean of the sample and 0.5 is the standard deviation of the sample.

As we have to find the weights that lie within the 2 standard deviations of the mean i.e

=9.5\pm 2(0.5)

=8.5,10.5

Among the given weights only 8.9 lbs, 9.5 lbs, 9.8 lbs, 10.4 lbs will lie within 2 standard deviations of the mean.
