Answer 1

18).the criteria used for rejecting the null hypothesis is called-TYPE I ERROR.For rejecting a null hypothesis at first we have to set the significance level then the probability of type I Error should be observed.it is a false positive finding of the hypothesis.it is used for rejecting the null hypothesis.

19).the smaller the p value-THE MORE EVIDENCE WE SHOULD REJECT THE NULL HYPOTHESIS.for rejecting the null hypothesis and accepting the alternate hypothesis P value should be determined.if it is less than 0.05 or less than that then the null hypothesis should be rejected.

23).hospital autopies include-INPATIENTS AND OUTPATIENTS WHO DIE IN THE HOSPITAL.hospital autopies are perfotmed for knowing the cause of clinical death.it is best performed within 24 hours of death.for performing autopies a hospital pathologist is required who will perform hospital autopies of inpatient and outpatients of the hospital who dies at a same time..
