Answer 2

Answer: D

Not normal, because we expect fewer than 10 customers who do not want to order tickets digitally in both samples.

Explanation: Khan Answer

10% of customers in July would not want to order tickets digitally because 90% do. In an SRS of 70 customers, that means only 7 would not want to order tickets digitally. 13% of customers in August would not want to order tickets digitally because 87% do. In an SRS of 70 customers, that means only 9.1 would not want to order tickets digitally. Because both of these counts are less than 10, we can not assume normality.
