Solution

$\text{Discrete}$ data are restricted to defined separated values with a finite or countable number of different possible values, for example integers or counts.

$\textbf{Continuous}$ data are not restricted to defined separate values, but can occupy any value over a continuous range, for example decimal, rational or real numbers.

Solution

(a) Discrete, because the population is an integer and the integers are countable.

(b) Continuous, because the weight can take on decimal values (for example, 30.7 kg).

(c) Continuous, because the time can take on decimal values (for example, 1.5 hours or 168.5 minutes).

(d) Discrete, because the number of consumers is an integer and the integers are countable.
