The coat color of black bears depends on a gene with two alleles. Allele B is dominant and confers black coat, whereas allele b is recessive and homozygous bears have white coats (albino black bears, I know it sounds weird but it is true). As we know from genetics each bear has two alleles and the coat colors are as follows: BB-black; Bb-black; bb-white. A researcher obtained the following data for the genotypes (BB, Bb or bb) of black bears: Genotype Number of bears BB 42 Bb 24 bb 21 You are performing the following hypothesis test: H0: The genotypes of the bears follow a binomial distribution, with a probability of receiving the b allele equal to the observed proportion of the b allele in the population. HA: The genotypes of the bears do not follow a binomial distribution What is the expected frequency of bears with genotype BB, Bb, and bb? Give the absolute expected frequency (number of bears) not the fraction/proportion of BB bears
Due to the alarming cases of Covid-19, a researcher wanted to study the characteristics of the patients in NCR infected by the virus. Lilliefors, a researcher, considered the following variables: M: age bracket (0-19, 20-39, 40-59, 60 and above) N: last country visited in the past 3 months O: number of days quarantined after manifestation of symptoms P: current status of the patient (mild, moderate, severe) 6. To answer the objective of the study, Lilliefors used different data collection methods. First, she gathered information about the variables of interest by letting the patients answer a self-administered questionnaire. Second, to supplement the data she gathered, she collected the sociodemographic profile of the patients using the data from the Department of Health. The methods of data collection used by Lilliefors are ________. A. objective and subjective, respectively B. subjective and objective, respectively C. objective and use of existing records, respectively…
Some researchers have conjectured that stem-pitting disease in peach tree seedlings might be controlled with weed and sol treatment. An experiment was conducted to compare peach tree seedling growth with sol and weeds treated with one of two herbicides. In a field containing 20 seedlings, 10 were randomly selected from throughout the field and assigned to receive Herbicide A The remaining 10 seedlings were to receive Herbicide B. Soil and weeds for each seedling were treated with the appropriate herbicide and at the end of the study period the height (in centimeters) was recorded for each seedling. A box plot of each data set showed no indication of non-Normality. The following results were obtained: x (cm) s (cm) Herbicide A 945 10 Herbicide B 109.1 A 95% confidence interval for ug - Ha is given by which of the following expressions? (Use the conservative value for degrees of freedom) (109 1-94 5) t1 96 (109 1-94 5) + 2 263 109 1- 94 5)2196, . (109 1- 945)2262, (109 1- 94 5)
I read about an antiviral drug called Paxlovid which can be given to high-risk individuals early after exposure to Covid-19 and is said to be protective against serious illness. A group of 1219 high-risk people were selected and 607 were given Paxlovid and 612 were given a placebo. After 28 days, nobody given Paxlovid had died and 6 were hospitalized. Among the placebo group, 10 had died and 41 were hospitalized. Our goal is to compare the difference in these proportions and assess the significance of the differences. We will add the steps as we go. What makes sense as a null hypothesis and alternative hypothesis? 2. What would be a good level of significance, and what is the critical value?
The Ministry of Health Malaysia is interested in the post-shot side effects of a particular Covid-19 vaccine on teenagers. The manufacturer of a particular vaccine claims that 50% of the second dose recipients would develop mild side effects than others. The Covid-19 working group performed a hypothesis test to determine if the claimed percentage by the vaccine manufacturer is trustworthy. They sampled 100 teenage vaccine recipients and found that 53 of the recipients had mild side effects after their second dose of Covid-19 vaccine administration. A 5% level of significance was chosen for the hypothesis test. iv. Illustrate the level of significance and the critical value in a graph.
The improved crop varieties are evaluated at farmers fields before their release for a large scale production. The claim made by a chickpea breeder is that, on average, her improved variety produces higher yield of chickpea compared to the local variety grown by farmers in her region. To examine her claim, the improved variety of chickpea was evaluated at 25 randomly selected farmer-fields (farms) in that region. Each field was divided into two parts, one part of the field was randomly assigned to the improved variety to be grown under a crop management practice recommended for this variety, and the other part to the local variety with an ongoing practice followed for it. You may note there were 25 different fields and the two varieties were grown within each of them. The chickpea yields of the two varieties were measured, in kg per hectare, from each of the fields. The following R- code outputs contain the information that you may use to answer the questions. The data vectors,…
A small epidemiological study was carried out in which we selected 100 women over the age of 60 with endometrial (uterus) cancer and 100 women over the age of 60 without endometrial cancer. All 200 women were contacted and asked, “Were you obese at age 50?” Among those with endometrial cancer, 75 said they were obese at age 50; amongthose without endometrial cancer, 60 said they were obese at age 50. Study design options: Ecological, Cross-sectional, Case Control, Prospective Cohort, RetrospectiveCohort, Randomized Clinical Trial
Sickle-cell anemia is a hereditary chronic blood disease that is extremely severe when an individual carries two copies of the defective gene. It is particularly common in countries plagued by malaria, a parasiticinfection transmitted by mosquitoes. A study in Africa tested 543 children for the sickle-cell gene and also for malaria. In Group 1 which consisted of 136 children with the sickle-cell gene, 36 children had severe malariainfections. Group 2 consisted of 407 children without the sickle-cell gene, and 152 of them had severe malaria infections. Conduct a test to determine if the proportion of severe malaria infections among children withthe sickle-cell trait is different from that among children without. Test at 5% level of significance. Question: What is your p value and t statistic ?
In a certain population, 11% of people are infected by a certainvirus. A virus detection test correctly detects 94% of cases in whichindividuals are infected, but mistakenly assigns 6% of positive resultsfor the uninfected (false positives). How likely is it that a person's testof this population give a positive result?
A university researcher knowledgeable in Chinese medicine conducted a study to determine whether acupuncture can help reduce cocaine addiction. In this experiment, 18 cocaine addicts were randomly assigned to one of three groups of 6 addicts per group. One group received 10 weeks of acupuncture treatment in which the acupuncture needles were inserted into points on the outer ear where stimulation is believed to be effective. Another group, a placebo group, had acupuncture needles inserted into points on the ear believed not to be effective. The third group received no acupuncture treatment; instead, addicts in this group received relaxation therapy. All groups also received counseling over the 10-week treatment period. The dependent variable was craving for cocaine as measured by the number of cocaine urges experienced by each addict in the last week of treatment. The following are the results. Acupuncture + Counseling Placebo + Counseling Relaxation Therapy + Counseling…
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?
