Answer #1

Solution:

1)

Critical value of  the significance level is α = 0.99, and the critical value for a left-tailed test is

= -2.583

2)

Critical value of  the significance level is α = 0.01, and the critical value for a right-tailed test is

= 2.518

3)

Critical value of  the significance level is α = 0.01, and the critical value for a left-tailed test

is

= 2.060
