Answer 1

Answer: (B), (C), (D)

The number of pizzas consumed in an hour in a restaurant.

In the collection of data, if every value obtained is a number, then the data constitutes numerical data.

And the non-numerical information that can be categorised into different groups falls under categorical data.

The above table represents the numerical data.

$\left(C\right)$ The heart rate of a group of $5$ people.
The above table represents the numerical data.

$\left(D\right)$ The number of pizzas consumed in an hour in a restaurant represents the numerical data i.e. 100/150.

Options (b.), (c.) and (d.) are correct choices.
