The following data were generated by the Weibull distribution of Exercise 4:

a. Obtain the maximum likelihood estimates of α and β, and estimate the asymptotic covariance matrix for the estimates.

b. Carry out a Wald test of the hypothesis that β = 1.

c. Obtain the maximum likelihood estimate of α under the hypothesis that β = 1.

d. Using the results of parts a and c, carry out a likelihood ratio test of the hypothesis that β = 1.

e. Carry out a Lagrange multiplier test of the hypothesis that β = 1.
