Construct the confidence interval for the population variance for the given values. round your answers to one decimal place. n = 10, s² = 36.4, and c = 0.9a) Calculate the critical value for a chi-square distribution with 9 degrees of freedom and 0.05 level of significance
b) Use the formula: lower bound = (n-1) * s2 / critical value
upper bound = (n-1) * s2 / critical value
c) Determine the confidence interval for the population variance: (a, b)
d) Round the values to one decimal place and conclude the confidence interval for the population variance
