Question

After recording the pizza delivery times from 2 different shops you concluded that one pizza shop has a mean of 46 minutes with a standard deviation of 3 minutes, The other shop has a mean of 45 minutes with a standard deviation of 19 minutes. Interpret these figures. Which shop would you order fro and why?

Answer 1

Hi There!

Explanation:

Standard Deviation - tells you the avearage of how far apart each number in the set values is away from the mean.

Shop 1:

Mean = 46

Standard Deviation = 3

Shop 2:

Mean = 45

Standard Deviation = 19

I would choose shop 1 because even though it has a 1 more minutre of the mean it has a less of a standard deviation. That means that Shop 2 has a set of values that are far apart than shop 1.

Answer:

Shop 1

Hope This Helps :)
