Random variables

Use the one-standard-deviation $$\displaystyle{x}^{{{2}}}$$ -test and the one-standard-deviation $$\displaystyle{x}^{{{2}}}$$-interval procedure to conduct the required hypothesis test and obtain the specified confidence interval. $$s=5$$ and $$n=20$$
a. $$\displaystyle{H}_{{{0}}}:σ={6},{H}_{{{a}}}:σ≠{6},α={0.05}$$.
b. 95% confidence interval

a. Do not reject $$\displaystyle{H}_{{{0}}}$$
