A procurement specialist has purchased 23 resistors from vendor 1 and 32 resistors from vendor 2. Let X1,1, X12X23 represent thevendor 1 observed resistances, which are assumed to be normally and independently distributed with mean 80 ohms and standarddeviation 1.7 ohms. Similarly, let X2,1, X2,2X32 represent the vendor 2 observed resistances, which are assumed to be normally andindependently distributed with mean 85 ohms and standard deviation of 2.1 ohms. What is the sampling distribution of X₁ – X₂?What is the standard error of X₁ - X₂?-iThe sampling distribution of X₁ X₂ is N(₁-x₂ ={Round the second answer to four decimal places.)The standard error of X₁ - X₂ is i0²₁-X₂ =i{Round your answer to three decimal places.)}

Exactly 12% of all applications were from minority members, and exactly 10% of the 1650 open positions were filled by members of the minority. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, where p is the proportion of minority member applications in a random sample of 1650 that is drawn from all applications. (b) Find the standard deviation of p. (c) Compute an approximation for P(p <0.1), which is the probability that there will be 10% or fewer minority member applications in a random sample of 1650 drawn from all applications. Round your answer to four decimal places.

Three components are randomly sampled, one at a time, from a large lot. As each component is selected, it is tested. If it passes the test, a success (S) occurs; if it fails the test, a failure (F) occurs. Assume that 82.0% of the components in the lot will succeed in passing the test. Let X represent the number of successes among the three sampled components. Find P(X= 3). (Round the final answer to three decimal places.)
