6.4.9. If *Ho: µ *= 30 is tested against *Ht=11. *> 30 using *n *= 16 observations (normally distributed) and if 1 - *f3 *= 0.85 when *f--L *= 34, what does o: ei!Ual? Assume that *a *= 9.

ti.4.10. Suptx)Se a sample of size 1is taken from the pdf *f y ( y ) *= *(1/>..)e- YI'-, **y *> 0, for the purpose o( testing

Ho:>.. = 1

versus Hi:>.. > 1

The null hypothesis will be rejected if *y *3.20.

(a) Calculate the probability of committing a Type I error.

(b) Calcu1ate the probability of committing a Type II error when ).. = f

(c) Draw a diagram that shows the *a *and {!calculated in Parts (a) and (b) as areas.
