Question
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 standard
deviation of 0.4. The 95% confidence for the average heights of the population is:
O[1.8532, 1.9642]
[1.5762, 1.9397]
[1.7345, 1.8301]
[1.7108, 1.7892]
