Question

QUESTION 2 A commonly prescribed drug for relieving nervous tension is believed to be only 60% effective. Experimental results with a new drug administered to a random sample of 100 adults who were suffering from nervous tension show that 69 received relief. Is this sufficient evidence to conclude that the new drug is superior to the one commonly prescribed Thus we might test Ho: P = 0.6 against the alternative H1; p > 0.6. Use a 10% level of significance (a=0.1). The value of the test statistic is A1.22 B. 1.02 C. 1.84 D.1.43

Answer 1

Qus: find the value of test statistics ang give the conclusion

Solution:

z is 1.84 greater that 1-28 g Since computed value of it is significant We may Reject the Null flysetbexie at 104. level of significance so option 'c' is correct
