B). Use THE CONCEPT OF COMPLEMENTARY EVENTS TO

Choose: IF THE PROBABILITY OF A PERSON GETTING

Individual NOT GETTING SICK?

Use THE FORMULA: P(SICK) + P (NOT SICK) = 1

Subjective COVID-19 testing is required for understudies, labor force, and staff at IUPUI. Acknowledge that 10% of the general population as of now has the disease in its system. A particular COVID test produces positive results 15% of when the individual doesn't actually have the disease, and it produces adversarial results 2% of the ideal chance for people who truly have the contamination. Given that an individual gets an opposite test result, what is the probability that the individual is truly polluted with the disease? Round your reaction to 4 decimal spots

The yearly pay for a particular occupation has a normal scattering with a mean of $54,000 and a standard deviation of ?=$5000. What is the probability that the mean pay of a discretionary picked test has some place in the scope of $49,000 and $56,150?

1. (30%) Please introduce the following methodologies. You should specify the purpose, moti- vation and idea of each method and briey describe the steps of each method. (a) Regression analysis by the principal component. (b) Regression analysis by using the stepwise regression. (c) Regression analysis by using the LASSO regression. Average Age and Length of Service The data show the average ages and lengths of service in months. Age 24.9 25.7 26.2 26.6 27.1 Time 66.4 69.4 73.9 89.5 81.3 Send data to Excel The correlation coefficient for the data is r = 0.821 and a # 0.05. Should regression analysis be done? The regression analysis should not be done. O The regression analysis should be done. Find the equation of the regression line. Round the coefficients to at least three decimal places. y =atbx b =The correlation coefficient for the data is r = 0.821 and a =0.05. Should regression analysis be done? The regression analysis should not be done. O The regression analysis should be done. Find the equation of the regression line. Round the coefficients to at least three decimal places. y'= atbx b If a service person is 26.2 years old, predict the time that the person will serve. Round the answer to at least one decimal place. The service person will serve months.Regression analysis probability question Suppose When doing regression analysis you obtain the regression equation y=10.0x+13 and an r squared value of 0.64. What is the correlation of your data set? A. 0.8 or -0.8 B. 0.8 only C. 0.64 D. 13
