18. The criterion used for rejecting the null
hypothesis is called _____.
a. Alternate hypothesis
b. Type I error
c. Significance level
d. Standard error of the mean
19. The smaller the p value _____.
a. The more evidence we should reject the null
hypothesis
b. The less evidence we should reject the null
hypothesis
c. The more likely it is that the results are not
significant
d. Has no relationship with significance
23. Hospital autopsies include which of the
following:
a. Inpatients only
b. Inpatients, outpatients, and home care
patients
c. Inpatients and outpatients who die in the
hospital
d. Inpatients and any other patient who has at some
time been a hospital patient
24. A hospital-acquired infection is also called
which of the following?
a. Nosocomial death
b. Post-operative infection
c. Nosocomial infection
d. Post-operative death
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..
24).a hospital aquired infection is also called as_ NOSOCOMIAL INFECTION. When a patient stays at the hospital environment for long days he can develop several infection from the hospital environment that is called hospital aquired infection.

3. The type of statistics that describes the characteristics of a group or population is called _____. a. Inferential statistics b. Descriptive statistics c. Generalized statistics d. Mathematical statistics 6. Which of the following is not used in figuring occupancy rates? a. Inpatient service days b. Bed count days c. Discharges d. Days in a period 9. The adjusted hospital autopsy rate includes _____. a. Patients whose bodies are available for hospital autopsy minus coroner’s cases b. Patients whose bodies...
13) Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. Suppose you wish to test the claim that μd, the mean value of the differences d for a population of paired data, is greater than 0. Given a sample of n = 15 and a significance level of α = 0.01, what criterion would be used for rejecting...

Explain what a P-value is. What is the criterion for rejecting the null hypothesis using the P-value approach? Explain what a P-value is. Choose the correct answer below. OA. A P-value is the probability of observing a sample statistic as extreme or more extreme than the one observed under the assumption that the statement in the null hypothesis is true B. A P-value is the number of standard deviations that the observed proportion is from the proportion stated in the...
The higher the alpha level, a. the lower the probability of rejecting the null hypothesis. b. the greater the probability of rejecting the null hypothesis. c. the larger the sample size has to be to reject the null hypothesis. d. the more desirable the two-tailed test. When solving the formula for finding Z(obtained) with sample proportions in the two-sample case, we must first estimate a. the population proportion. b. the critical region. c. the ratio of the sample proportions. d....
The probability of mistakenly rejecting the null hypothesis at least once after doing several hypothesis tests is called what? a) The Familywise Error Rate b) The Hypothetical Significance c) None of the Above **Note, didn't list one of the options because it is wrong: "the significance level"
The null hypothesis and the alternate hypothesis are: H0: The frequencies are equal. H1: The frequencies are not equal. Category f0 A 25 B 20 C 25 D 10 1) State the decision rule, using the 0.01 significance level. Reject H0 if chi-square > _____ 2) Compute the value of chi-square.
4. Hypothesis testing for a Population proportion Write down the null and alternate hypotheses for part a) and b) first. a) points) According to a 2005 survey conducted by the Association for Dressings and Sauces, 85% of American adults cat salad at least once a week. A nutritionist suspects that the percentage is lower than this. He conducts a survey of 200 American adults and finds that 158 of them eat salad at least once a week. Using either the...
a is .05 and N-25, the probability of rejecting the null hypothesis if the mull hypothesis is true is: a. .os b..95 c. 05/25 - 01 d..95/25 = .19 e. insufficient information to answer as the popu 4. The sampling distribution of the mean always has the same distribution of the raw scores. a. mean b. standard deviation c. skew d. a and b e. all of the above S. If the sample size on which a standard deviation is...
statistics help 7) Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test ie, describe the values of the test statistic that would result in rejection of the null hypothesis Suppose you wish to test the claim that the mean value of the differences d for a population of paired data, is greater than 0. Given a sample of n-15 and a significance level of a-001, what criterion would be used for rejecting the null hypothesis...
