To predict how many customers out of the 350 will buy two or more pairs, you need to find 24% of the 350 customers: 24% * 350 = 84 Customers. So, it is predicted that 84 customers will buy a second or more pair.
However, 107 customers bought a second pair. To find how many more from the predicted amount, you need to find the difference: 107 - 84 = 23 customers. So, 23 more customers bought a second pair than the predicted amount (of 84).
Therefore, yes, more customers than norma bought two or more pairs.
Hope this helps. :)
