Assignment task:
Instructions:
Determine the interval of 95% confidence for the average heights of the population using the following information:
The average height of a random sample of 400 people from a city is 1.75 m. It is known that the heights of the population are random variables that follow a normal distribution with a variance of 0.16.
Confidence Interval Formula = ( x¯ - z * o / √n) to ( x¯ + z * o / √n)
