A study claims that over 40% of those who suffer from osteoarthritis receive measurable relief from an ingredient produced by a particular species of mussel. To test this claim, the mussel extract is to be given to a group of 63 osteoarthritic patients and the critical region is defined to be x< 19, where x is the number of osteoarthritic patients who receive relief. If x is not in this region, we shall not reject the null hypothesis that p = 0.4; otherwise, we conclude that p<0.4. (a) Evaluate a, assuming that p = 0.4. (b) Evaluate ß for the alternative p=0.3.

(b) B = (Round to four decimal places as needed.)
