The morning and evening body temperature measurements are paired.

Step-by-step explanation:

We are given the following information in the question:

A sample of 40 indoor cats is obtained. Each cat's body temperature measured in the morning and again in the evening.

Paired or dependent Variables:

• This means that there are same participants more than once in a test.
• They are also known as related groups.
• Dependent variable are related groups where two groups are referred to groups of participants that are measured at two different points of time or under two different condition.
• There is only one group of variables, but there are two conditions associated or time interval.
