critical values χ2L and χ2R for the given confidence level c and sample size n. c=0.8​, n=30

Assessment Task: Statistical Intervals 1. A random sample of size n1 = 25, taken from a normal population with a standard deviation ol = 5, has a mean 1 = 80. A second random sample of size n2 = 36, taken from a different normal population with a standard deviation o2 3, has a mean 2 = 75. Find a 95% confidence interval for ul - u2 %3D
