Multiple myeloma, or blood plasma cancer is characterized by increased blood vessel formulation (angiogenesis) in the bone marrow that is a predictive factor in survival. One treatment approach used for multiple myeloma is stem cell transplantation with the patient’s own stem cells. The data in the table below represent the bone marrow micro-vessel density for patients who had a complete response to the stem cell transplant and at the time the complete response was determined. Patient Before After 1 158 284 2 189 214 3 202 101 4 353 227 5 416 290 6 426 176 7 441 290 Please show work done by hand and/or using Excel formulas, graphing calculator unavailable. At the 0.05 level of significance, is there evidence that the mean bone marrow micro-vessel density is higher before the stem cell transplant than after the stem cell transplant?
.A new, miracle diabetes drug that diminishes major symptoms of diabetes has been approved by the FDA. Health care professionals and researchers believe that the new drug will prolong lifespan of diabetes patients. If the population is in steady state and the incidence is constant, what will the effect of this new drug be on the prevalence of diabetes in the population? Explain.

A blog noted that "there has been increasing anecdotal evidence that vitamin C may still be useful as an anticancer medicine if used in high concentrations and given directly into the vein (intravenously)." Use this information to answer the questions below. Question content area bottom Part 1 Explain what it means that there is "increasing anecdotal evidence" that Vitamin C may be a useful anticancer medicine. A. There is no evidence that shows Vitamin C may be a useful anticancer medicine. B. There is scientific evidence that Vitamin C is a non-useful anticancer medicine. C. There is an increase in rigorous or scientific analysis that shows Vitamin C may be a useful anticancer medicine. D. There is an increase in observations or personal experiences that shows Vitamin C may be a useful anticancer medicine. Part 2 How does anecdotal evidence contrast with scientific evidence? A. They are stories about individual cases.…

Types of samplingIn each of the following exercises, identify the type of sampling to which the premise refers: random, systematic, convenience, stratified, by cluster:a) The sample is homogeneous and results are as accurate as those of a simple random sampling, but with a smaller sample size.b) It tends to provide better results when the elements within the clusters are not similar.c) A professor conducting research at a university can use student volunteers to form a sample, simply because they are available to her.
If arrivals occur at a mean rate of 2.6 events per minute the exponential probability of waiting more than 1.5 minutes for the next arrival is is a .0202 or .0122 or .0535 or .2564
Data originally from DASL http://lib.stat.cmu.edu/DASL/Datafiles/CancerSurvival.html (Links to an external site.). Some bronchial cancer patients had the following survival times (in days) after receiving a certain treatment: 20, 37, 63, 64, 72, 81, 138, 151, 155, 166, 166, 223, 245, 246, 450, 459. (The second instance of “166” is not a mistake.) Do these numbers suggest that the average survival time, for all bronchial cancer patients who receive that treatment, is significantly different from 200 days?
