- This is part of probstat.
Poisson and exponential random variables
Hypothesis testing
1. We are interested in testing that a population has mean zero. We know that the variance of the population is 17. If we decide to take a sample of size 15, design a hypothesis testing procedure with the level of significance .
State the null hypothesis clearly and describe the criteria for accepting/rejecting the null hypothesis.
