A medical study is conducted on people who are tested positive for Covid-19. The study found that 15% of people have low-level in Vitamin D, 26% have medium-level in Vitamin D. and 59% have normal-level of Vitamin D. The study also found that persons who • Have low-level in Vitamin Dare at 91% risk of dying from Covid-19. • Have medium-level of Vitamin D are at 50% risk of dying from Covid-19. • Have normal-level of Vitamin D are at 14% risk of dying from Covid-19. 1. A person who is tested positive for Covid-19 is chosen randomly, what is the probability he will die from Covid-19? C0.5167 00.3491 C0.039 C0.5 2. A person who is tested positive for Covid-19 died, what is the probability he had low-level in Vitamin D? C0.391 C0.1365 C.15 3.

A new vaccine against the coronavirus has been developed. The vaccine was tested on10,000 volunteers and the study has shown that 65% of those tested do not get sick from thecoronavirus. Unfortunately, the vaccine has side effects and in the study it was shown thatthe probability of getting side effects among those who did not get sick is 0.31, while theprobability of getting side effects among those who got sick from corona despite vaccinationis 0.15. (b) What is the probability that a randomly vaccinated person does not become ill with thecoronavirus and does not get side effects? (c) What is the probability that a randomly vaccinated person gets side effects? (d) What is the probability that a randomly vaccinated person who has not experienced sideeffects does not become ill with the coronavirus?
An optometrist suspected that the reading habits of all the first year optometry students from DDC have a bad effect to their eye vision that could possibly affect both of their academic and non-academic performance. Upon conducting the study, he found out the following results; 1. 75% of the total number of first year optometry students from DDC, 25% were males and 50% were females, have bad eye vision due to their reading habits and got poor academic performance but a satisfying performance in non-academic activities. 2. The researcher got a 30% sample out of the 100% population and found out that 20% of the sample were females and 10% were males with bad eye vision due to their reading habits and got poor academic performance but satisfying non-academic performance. 3. The conclusion was, the reading habits of the first year optometry students from DDC had bad effects to their eye vision. This was one of the reasons that the students have poor performance in academic activities…
The authors of the article "Adjuvant Radiotherapy and Chemotherapy in Node-Positive Premenopausal Women with Breast Cancer"† reported on the results of an experiment designed to compare treating cancer patients with chemotherapy only to treatment with a combination of chemotherapy and radiation. Of the 154 individuals who received the chemotherapy-only treatment, 76 survived at least 15 years, whereas 98 of the 164 patients who received the hybrid treatment survived at least that long. With p1 denoting the proportion of all such women who, when treated with just chemotherapy, survive at least 15 years and p2 denoting the analogous proportion for the hybrid treatment, p̂1 = (rounded to three decimal places) and p̂2 = (rounded to three decimal places). A confidence interval for the difference between proportions based on the traditional formula with a confidence level of approximately 99% is 0.494 − 0.598 ± (2.58) (0.494)(0.506) 154 + (0.598)(0.402) 164…
While some western, traditional, or home remedies alleviate symptoms of mild COVID19, there are no vaccines that have been shown to prevent the disease. However, there are several ongoing clinical trials of these potential drugs. Four laboratories were being used to test the drugs that have proved effective in treating “corona patients” in four different countries namely United States of America, England, China, and Israel. As part of the study to determine whether or not they give on the average the same results. The results for the number of days taken by mild cases to recover were as follows: Laboratory A B C D 3 7 1 7 6 9 4 3 5 8 5 5 4 4 2 6 3 5 3 7 Perform the analysis of variance and give conclusions concerning the drugs at the 0.05 level of significance
IL-6 is a cytokine released as an immune response to infection. Elevated IL-6 is suggested to be predictive of severe illness with Covid-19. Suppose we wanted to conduct a study to see if this is true among patients with Covid-19 in Florida. Assuming from a previous studies in other areas of the US, the mean IL-6 id 8.87 pg/mL (s.d. = 6.09 pg/mL) among individuals with moderate disease and 7.66 pg/mL (s.d.= 4.97 pg/mL) among individuals that are asymptomatic or have mild illness, how many people in total, would need to enroll in our new study to determine if there is a difference in means with 95% confidence and 80% power?

Age-related macular degeneration (AMD) is a common eyedisease among the elderly that can lead to partial or total lossof vision. It is well known that smoking and excessive weighttend to be associated with higher incidence rates of AMD.More recently, however, several genes have been found tobe associated with AMD as well. One gene that has beenconsidered is the Y402H gene. There are three genotypesfor the Y402H gene—TT, TC, and CC. The relationshipbetween AMD and the Y402H genotype is as follows: Y402H AMD=yes AMD=no TT (wild type) 41 380 YC 119 527 CC 121 278 Total 281 1185 (1) What is the relative risk for AMD for the CC genotype compared with the TT genotype?

The National Health and Nutrition Examination Study (NHANES) had a random sample of 9317 participants recall their diet over the past 24 hours. The information in this sample was used in a recent study that found that, on average, 57.9% of the calories eaten by participants were obtained from ultra-processed foods that include substances not used in culinary preparations, such as flavors, colors, sweeteners, emulsifiers, and other additives. One of the limitations of the study reported by the authors was the dependence on the dietary recall of individuals. The authors were concerned with: (Choose one and explain why in 1-2 sentances) A) response bias B) undercoverage C) overstratification

Is There a Genetic Marker for Dyslexia? A disruption of a gene called DYXC1 on chromosome 15 for humans may be related to an increased risk of developing dyslexia. Researchers1 studied the gene in 109 people diagnosed with dyslexia and in a control group of 195 others who had no learning disorder. The DYXC1 break occurred in 10 of those with dyslexia and in 5 of those in the control group.1Science News, August 30, 2003, p 131. (a) Is this an experiment or an observational study?

Of a random sample of 100 college students, 35 expected to achieve a higher standard of living than their parents, 43 expected a lower standard of living, and 22 expected about the same standard of living as their parents. Do these data present strong evidence that, for the population of students, more expect a lower standard of living compared with their parents than expect a higher standard of living?
Photon is a training device that is designed to improve a user's reaction time. Similar devices have been criticized for being too easy to master, but the makers of Photon say that their device is built to give most users room to improve. The makers say that even among professional athletes, the proportion, , who can score the top ranking of "light speed" is less than 16%. A random sample of 110 professional athletes is chosen, and 14 score a ranking of "light speed" while using the device.Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the level of significance, to support the claim that the proportion of all professional athletes who can score a ranking of "light speed" is less than 16% .
