Answer:
D: How many hours did you spend watching TV today?
Step-by-step explanation:
Statistical questions can be identified by the fact that they can have multiple answers. This question could be answered in many different ways. "Did you watch four hours of TV today?" is a yes or no question (which makes it non statistical), "Did you watch TV today?" is the same way. "Did you watch five or six hours of TV today?" also only has two possible answers, which means it is non statistical.
D: How many hours did you spend watching TV today? is the only option that has multiple possible ways of answering
Fixed Charge FC = $50
$12 per hour.
Let number of hours = n
Total Charge TC = 50 + 12n
For a total charge of $115.
50 + 12n = 115
12n = 115 - 50
12n = 65
n = 65/12
n = (65/12) hours.
Number of minutes = (65/12) * 60, since 1 hour = 60 minutes
= 65*5 = 325 minutes

The original statement is true only if:
- England is a country and Africa isn't
- Africa is a country and England isn't
- Neither of them are countries
Options a and d are equivalent:
![P\implies Q \iff \lnot Q \implies \not P](https://tex.z-dn.net/?f=P%5Cimplies%20Q%20%5Ciff%20%5Clnot%20Q%20%5Cimplies%20%5Cnot%20P)
and they both are true in the same cases as above.
Option c is also fine, because it is false only if both England and Africa are both countries, just like the original statement.
Option b, instead, is true only if neither of the two options are countries, so it doesn't cover the cases where only one of the two is a country.
