A steel manufacturer is testing a new additive for manufacturing an alloy of steel. The jointprobability mass function of tensile strength (in thousands of pounds/in?) and additiveconcentration isTensile StrengthConcentration of Additive1001502000.110.020.050.060.040.010.080.100.170.060.040.080.080.040.140.12What are the marginal probability mass functions for X (additive concentration) and Y(tensile strength)?Are X and Y independent? Explain.a.b.Given that a specimen has an additive concentration of 0.04, what is the probabilitythat its strength is 150 or more?Given that a specimen has an additive concentration of 0.08, what is the probabilitythat its tensile strength is greater than 125?A certain application calls for the tensile strength to be 175 or more. What additiveconcentration should be used to make the probability of meeting this specification thegreatest?C.d.e.

Clinical research attempts to identify the risks of exposure tothe population in the workplace. In a group of 46 menBetween the ages of 25 and 36, changes in the function of their lungs have been measured. One of the variables of interest was the volumeexhalation force (VFE), which is the volume of air exhaled per second. At the end of a certain period, it was found that the VFE of `this sample decreased with an average of 0.27 liters and a deviation0.52 liter sample type. We know that the VFE increases by 0.1liter in healthy men of the same ageduring the same period of time. Can we conclude that the middle ofwork of this group plays a significant role in the growth ofVFE greater than 0.1 liter? Choose the appropriate hypothesis testto do. Give the value - P and your conclusion. Take α = 0.02.
