#task 7Suppose that the heights of 100 boys at X School represent a random sample of the
heights of all 1500 students at the school. The mean and the standard deviation of the sample
heights are 1.70m and 0.2m, respectively. Use Python to find the 95% confidence interval for
estimating the mean height of the X School students. Hints: you may import scipy.stats as st
and import numpy as np. Use st.norm.ppf to get the value of 𝑧1−0.05/2.
