c.What would a Type II error be in this situation? What are the effects of

Answer 1

Ans:

a)

b)Type I error:

When we conclude that less than half of patients who take this new drug for treating Alzheimer’s disease will experience nausea,but in actual,more than half or equal to half will experience nausea.

It means patients are unnecessarily taking new drug as there are no effects in actual.

c)

When we conclude that more than half or equal to half of patients who take this new drug for treating Alzheimer’s disease will experience nausea,but in actual,less than half will experience nausea.

It means we are declaring a effective drug as ineffective drug and suggesting not to use as there are no effects,but in actual it is effective.
