Answer #1

What is the most appropriate statistical method to find out if cancer patients lived longer than 548 days after receiving ascorbate treatment?

a. A hypothesis test.

For the given scenario, we need to use upper tailed test for checking the given claim. We don’t use confidence interval in the case of one tailed hypothesis. For the ANOVA test, we need more than two population means for comparison.

What information in the output of this statistical method gives the answer?

a. The p-value.

Explanation:

The p-value of this statistical method gives the answer because we compare the p-value with alpha value and then decide whether reject or do not reject the null hypothesis.

How many tails are needed to find out if patients who took ascorbate lived longer than 548 days? Select one: a. One tail, because the researcher only wants to know if life expectancy increased after ascorbate treatment. b. Either one-tail or two-tail, because both situations will tell if life expectancy changed. c. Two-tail, because the purpose of the study was to find if life expectancy changed. d. Either one-tail or two-tail, because both situations give the same answer.

Please read the question carefully. Problem: Proportion of ”Cured” Cancer Patients: How Does Canada Compare with Europe? Lung cancer remains the leading cause of cancer death for both Canadian men and women, responsible for the most potential years of life lost to cancer. Lung cancer alone accounts for 28% of all cancer deaths in Canada (32%. in Quebec). Most forms of lung cancer start insidiously and produce no apparent symptoms until they are too far advanced. Consequently, the chances of...

Patients recovering from an appendix operation normally spend an average of 6.3 days in the hospital. The distribution of recovery times is normal with a σ = 2.2 days. The hospital is trying a new recovery program designed to lessen the time patients spend in the hospital. The first 25 appendix patients in this new program were released from the hospital in an average of 5.5 days. On the basis of these data, can the hospital conclude that the new...

2. For the following experiment/question, pick the most appropriate statistical test. You have the following statistical tests as choices: some may be used more than once, others not at all. Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., “the data are not at all normal”) or otherwise indicated (viz., by the inspection of the data) which would indicate a strong and obvious violation of an assumption. This means...
