The personnel department of a large manufacturing firm selected a random sample of 23 workers. The workers were interviewed and given several tests. On the basis of the test results, the following variables were investigated: X2 = manual dexterity score, X3 = mental aptitude score, and X4 = personnel assessment score. Subsequently, the workers were observed in order to determine the average number of units of work completed (Y) in a given time period for each worker. Regression analysis yielded these results: Y = -212 + 1.90X2 + 2.00X3 + 0.25X4, R2 = .75. (.050) (.060) (.20) The quantities in parentheses are the standard errors of the regression coefficients. The standard error of the regression is 25, and the standard deviation of the dependent variable is 50. Which variables are making a significant contribution to the prediction of units of work completed at the .01 significance level (two tailed)? Group of answer choices All three variables. Manual dexterity and personnel assessment. Manual dexterity and mental aptitude. Personnel assessment. None of the variables are statistically significan

Texts: ZOOM Problem 1: Blood thinning medicines are administered to patients who are at a risk of a heart attack. To check the efficacy of the drug, one needs to draw blood from the patient and measure its viscosity. One common method for doing so is using a Parallel Disc Viscometer (shown schematically in the figure below). The sample of fluid whose viscosity is to be measured is present in the gap of thickness H between 2 discs of radius R. One measures the torque Tz required to turn the upper disc at an angular velocity. Torque Tz Angular velocity Disc at z=H rotates Fluid with density p and viscosity μ is held in place by surface tension Disc at z=0 is stationary (a) State the assumptions that you can make about the flow in the system if the fluid happens to be defibrinogenated blood. [10 points] (b) Obtain the proper simplified form of the Equation of Continuity [10 points] (c) Obtain the proper simplified form of the Navier-Stokes Equation(s) [3x10=30 points] (d) Write down ALL the boundary conditions needed to solve the equations above [10 points] (e) If the velocity distribution in the system can be given by the equation Ve (r, z) = r.f(z), determine the function f(z) by solving the equations derived in parts (b) and (c) [20 points] (f) Determine the pressure profile [Pr,=] implied by the velocity profile. [10 points] (g) Is the pressure profile obtained above consistent with your assumptions (if any) regarding Vr and Vz? If not, can you explain the inconsistency? [10 points] (h) Find the shear stresses (as functions of r and z) on both the lower and the upper plates [2x10=20 points] (i) Show that the working equation for calculating the viscosity is: μ = (2 H Tz) / (π R) [20 points]

Q1. [CLO3, PLO2 You are required to make GUI based calculator that will perform the basic calculation, in addition with that also add features of currency convertors where you will enter any currency and on pressing any other currency button it will convert, for example if I enter 100 US dollars in pressing PKR, it will convert to it and on mean time if I press British Pounds it will give me the converted amount. You have to use the concept of dll here. Note: add currency like dollars, pounds, PKR, Euro and Dirham.
