A study was carried out to determine the efficacy and efficiency of the EAT-40 Test to detect eating disorders, where 2641 examinations of the EAT-40 Test were carried out and compared with the results of the gold test Bulimia Test - Revised (BULIT -R). The results obtained are the following: of those that were applied the EAT-40 Test came out normal (-) 1738, of which 1251 were healthy and of those that came out abnormal (+) in the EAT-40 Test, 634 if they were sick. What is the specificity of the test? How many false negative results were found? How many patients developed the pathology? How many patients did not develop the pathology? What is the sensitivity of the test? What is the positive predictive value of the test? How many patients tested positive?

Suppose a researcher conducted a study examining the effectiveness of font type (OpenDyslexic vs. Times New Roman) on reading comprehension for 20 students with dyslexia. After reading a passage in one of the two fonts, 10 students in each of the two font conditions completed a brief reading comprehension test of 15 questions. The number of correctly answered questions for each student is given in the table below: Complete the following in the context of conducting data analysis/ a. Calculate the average number of correct test questions for each group b. Calculate the standard deviation for each group c. Calculate the median and mode for both groups d. Calculate the interquartile range for each group OpenDyslexic 10 9 11 8 24867 12 14 Times New Roman 6675 & Na 43 4 2 8 9
A researcher measures expression levels of 20000 genes for 'no treatment' case and 'drug treatment case in a cell line, experiment was made in 4 replicates. The researcher asks for your help in: a. How to compare expression level of each gene in no treatment and drug treatment cases statistically? Which hypothesis test methods can be used?
Twenty middle-aged men with glucose readings between 90 milligrams per deciliter and 120 milligrams per deciliter of blood were selected randomly from the population of similar male patients at a large local hospital. Ten of the 20 men were assigned randomly to group A and received a placebo. The other 10 men were assigned to group B and received a new glucose drug. After two months, posttreatment glucose readings were taken for all 20 men and were compared with pretreatment readings. The reduction in glucose level (Pretreatment reading − Posttreatment reading) for each man in the study is shown here. Group A (placebo) reduction (in milligrams per deciliter): 12, 8, 17, 7, 20, 2, 5, 9, 12, 6 Group B (glucose drug) reduction (in milligrams per deciliter): 29, 31, 13, 19, 21, 5, 24, 12, 8, 21 Part A: Do the data provide convincing evidence, at the α = 0.02 level, that the glucose drug is effective in producing a reduction in mean glucose level? Part B: Create and interpret a 98%…
A 9-year study was conducted in Sweden, comparing 21,088 women who had mammograms with 21,195 who did not. Of the women who underwent screening, 63 died of breast cancer, compared with 66 deaths among the control group. (New York Times, Dec 9, 2001). Do these results support the effectiveness of regular mammograms in preventing deaths from breast cancer? Evaluate with a TI 83.
(b) A rescarcher supccts that the fish in a particular elevated wetland have elevated mercury level. To confirm that, five striped bass in that wetland were caught and their tissues were tested for mercury. Then four striped bass in an unpolluted wetland were also caught and tested for the purpose of comparison. Table QI shows the fish mercury levels in mg/kg. Table QI shows the fish mercury levels in mg/kg. Sample from polluted wetland Sample from unpolluted wetland 0.580 0.382 0.711 0.276 0.571 0.570 0.666 0.366 0.598 Construct the 95% confidence interval for the difference in the population means. Then, test at the 5% level of significance, whether the researcher's suspicion is valid. Assume that the population variances are equal.
7/8) individuals tend to vary in their taste sensitivity. Is it possible that this trait may be linked to a person’s genetics? A scientist identified the genotype of 30 individuals for a gene she believes to be responsible for taste sensitivity. She compares taste sensitivity across the homozygous dominant, heterozygous, and homozygous recessive individuals. Q) What is the explanatory variable here? Q) What kind of variable is the subject’s genotype?

Suppose we have a balanced one-way ANOVA, with 10 observations in each of 4 groups. The total sum of squares was found to be 2000. The sum of squares due to error (AKA residual) was found to be 900. What is the value of the one-way ANOVA F test statistic? (Give your numeric response to at least 3 decimal places. Give only the numeric response, and not any extra characters or symbols.)
