Answer 1

Q1. The statement is valid because since there are more empty spaces in the parking lot of Italian Restaurants than at a Shanghai Chinese restaurant, therefore, more people prefer Chinese food over Italian food.

The following are the possible misuse or misinterpretation that may exist:

1) Misleading data visualization- eg. There might be a possibility that the Italian Restaurant is considerably much bigger of a size than the Chinese restaurant.

2) Purposeful and selective bias- eg. There might be a possibility that the polls are taken on a weekend's busy time at the Chinese restaurant and during the early hours at the Italian restaurant.

Q2. The statement is valid because healthy snacking does not lead to an increase in weight.

The following are the possible misuse or misinterpretation that may exist:

1) Purposeful and selective bias- eg. There might be a possibility that the latter part of the statement is not authentic.
