Expert Solution
Step 1

Assumptions for t distribution are given below:

  • Samples are independently and randomly selected from the population.
  • Population standard deviation is unknown.
  • The sample size is smaller. That is, the sample size is less than 30.

Assumptions for normal distribution are given below:

  • Samples are independently and randomly selected from the population.
  • Population standard deviation is known.
  • The sample size is larger.
