Question

.

Answer 1

5.1 is correct for the mean

Answer 2

any ideas on how to find the variance?

Answer 3

good, that will get you the population variance

Answer 4

yes I think so

Answer 5

I'm getting 0.217857143, so yes

Answer 6

take the square root of the variance to get the standard deviation

Answer 7

what do you mean?

Answer 8

I would do the full decimal expansion then round when you're done

Answer 9

sqrt( 0.217857143 ) = 0.46675169308744 approximately

Answer 10

if you were rounding to 1 decimal place, then the std dev would be roughly 0.5

Answer 11

sure

Answer 12

Are you familiar with the normal distribution and the empirical rule?

Answer 13

have you heard of the bell shaped curve?

Answer 14

hmm seems odd how they ask you a question on something the lesson hasn't covered (yet)

Answer 15

but basically, the candies are distributed on this bell shaped curve
