Discrete math 22) A blood test is used to determine whether a person has a disease. 1% of the totalpopulation has the disease. If a person has the disease, then the probability that the testoutcome is positive is .95. If the person does not have the disease then the probabilitythat the test outcome is negative is .98. If a person takes the blood test and theoutcome is positive, then what is the probability that the person has the disease?a.b.C..99x.02(.01x.95)+(99x.02).99x.98(.01x.95)+(99x.98).01x.95(.01x.95)+(99x.02).01x.95d.CS Scanned with CamScanner

Reading is fundamental to a teenager's ability to perform well in school. Assume a researcher is interested in the ability of the number of books read over the summer to predict ACT Reading scores. Using a random sample of 10 random high school students the researchers recorded the number of books read over the summer and the students' ACT Reading scores. Books Read (X) ACT Score (Y) (X- Xmean) (Y - Ymean) (X-Xmean)(Y-Ymean) (X-Xmean)?

Allergic reactions to poison ivy can be miserable. Plant oils cause the reaction. Researchers at Allergy Institute did a study to determine the effects of washing the oil off within 5 minutes of exposure. A random sample of 1000 people with known allergies to poison ivy participated in the study. Oil from the poison ivy plant was rubbed on a patch of skin. For 500 of the subjects, it was washed off within 5 minutes. For the other 500 subjects, the oil was washed off after 5 minutes. The results are summarized in the following table.

LDL - low density lipoprotien - cholesterol is considered the bad cholesterol. A pharmaceutical company conducts a clinical trial on people with high levels of LDL cholesterol. The trial involves a random sample of n = 13 persons who have high levels of LDL. Each person has their LDL level measured prior to the beginning of the drug trial. Each person is then to take a new drug that is believed to lower ones LDL levels. After a period of 4-weeks, the LDL level of each person is measured again. The difference between the initial LDL level and the LDL-level four weeks after taking the drug is then computed. -0.44, -0.63,-0.73, 0.38, -0.21, 0.05, -0.53, -1.02, -0.3, -0.32, -0.06, -0.4, -0.63 Data from the sample, are saved in the Download .csv file. Assuming the difference in the LDL-levels is Normally distributed, find a 94% confidence interval for μ, the mean difference in the LDL-level of a person after taking the drug for four weeks.

The approximate values are both off by 100, therefore these values are equally accurate. Does this conclusion make sense? Why or why not? 4) For a 4-digit decimal machine numbers (with exponents in the range -6 ≤ n ≤ 6), find Largest possible number = ________________________ Smallest possible positive number = _____________________
