= 250
Sample size, n = 100
Alpha, α = 0.05
Sample standard deviation, s = 40
First, we design the null and the alternate hypothesis
Interpretation:
The null hypothesis state that sample belongs to the population and has a cholesterol level of greater than equal to 240 whereas the alternate hypothesis states that the sample does not belong to the population and have a cholesterol level of less than 240.
