Answer

Explanation:

Step1: Calculate percentage of shoppers without computer access at home

The number of shoppers without computer access at home is (12 + 81=93). The total number of shoppers is (150). The percentage formula is (\text{Percentage}=\frac{\text{Number of relevant cases}}{\text{Total number of cases}}\times100). So, (\frac{93}{150}\times 100 = 62).

Step2: Calculate percentage of shoppers with an e - mail account

The number of shoppers with an e - mail account is (48+12 = 60). Using the percentage formula (\frac{60}{150}\times100=40).

Answer:

(a) 62% (b) 40%
