Q.107 - The Practice of Statistics for AP

Question

Normal body temperature (8.3) Check that the conditions are met for performing inference about the mean body temperature in the population of interest.

Step-by-Step Solution

Answer

All conditions have been satisfied.

Step-1: Given Information

we have to Check that the conditions are met for performing inference about the mean body temperature in the population of interest. 

Step-2 Explanation

There are three conditions when a mean population significance test is performed: Random, Normal and Independent.

Random: Satisfied, since the sample given is a random sample.

Normal: Satisfied, as the sample size of $130$ is at least $30$ and therefore the distribution is about the standard.

 Independent: Satisfied since the $130$ -sample size is less than $10$ percent of the size of the population. Therefore, it is observed that all three conditions have been met.
