- Let's assume that there are 500 people in a population. The researcher has access to all 500 participants, and sends a questionnaire that is accessed by a hyperlink. Of the 500 possible subjects, 485 complete it. Does this mean that the results generated from this study will be highly-accurate? What might cause the study to be unreliable?If the alleles A and B of the cystic fibrosis gene occur in a population with frequencies p and 1 - p (where pis between 0 and 1), then the frequency of heterozygous carriers (carriers with both alleles) is 2p(l - p). Which value of p gives the largest frequency of heterozygous carriers?with out expand
- what happened to the 1(1-lambda) part in the first lineAccording to U.S. government statistics, mononucleosis (mono) is four times more common among college students than the rest of the population. Blood tests for the disease are not 100% accurate. Assume that the following table of data was obtained regarding students who came to a certain school's health center complaining of tiredness, a sore throat, and slight fever. Has Mono Doesn't Have Mono Totals Positive Blood Test 19 44 63 Negative Blood Test 46 29 75 Totals 65 73 138 If a student is selected from this group, find the probability that the test is positive, given that the student has mono.Obtain a family of equations
- At pandemic time of COVID 19 surveys are conducted in two townships which fall into the same Lusaka city. In Chawama, 175 tested positive out of a sample of 318 who were tested for COVID 19. In Kabulonga, 143 tested positive out of a sample of 307 who were tested for COVID 19. At the 5% level, is there a difference between the proportions of those who tested positive in each areaIf two brown mice are bred together, 35 of their 100 offspring are white. You hypothesize that the parents are heterozygous (Bb x Bb), support your claim using a chi square.This graph shows data from people from the sub-Saharan area of Africa who have contracted HIV. Outcomes for the patients were recorded as one of 4 mutually possibilities: alive and still in care at the original clinic, alive and still in care after transferring to a new clinic, alive but no longer visiting a clinic, or they’re dead. Keep in mind that this data were collected are from clinical records. Assume that the sample is a random representation of sub-Saharan Africans with HIV. Antiretroviral therapy is used to treat patients. What is the experimental unit? What are the variables (including the types)?
