7 Multiple Answer 1 point How would you guess that the binding of antigen to the variable region of a B-cell receptor might lead to that cells proliferation and differentiation into plasma cells and memory cells? A conformational change in transmembrane domain of the B-cell receptor contacting a cytoplasmic protein By triggering phosphorylation of a protein in that cell to expose a nuclear localization signal By binding to the B-cell receptor after it has been secreted as an antibody By binding to the B-cell receptor prior to completion of VDJ-recombination By ultimately leading to differential expression of genes in that cell involved in differentiation

Explain whether each of the following shifts the aggregate demand curve to the right or to the left. The Federal Reserve sells ​$1313 billion of U.S. Treasury securities. It would ▼ the interest​ rate, causing the AD curve to shift to the ▼ left right . Part 2 The federal government launches a massive program to rebuild the​ nation's highways. It would directly ▼ decrease increase aggregate​ expenditure, causing the AD curve to shift to the ▼ left right . Part 3 The federal government raisesraises the corporate profits tax. It would ▼ decrease increase the​ after-tax rate of return on investment​ projects, ▼ increasing decreasing investment spending and causing the AD curve to shift to the ▼ left right . Part 4 The foreign exchange value of the dollar risesrises. It would ▼ increase decrease the cost of U.S. exports and ▼ decrease increase the cost of foreign​ imports, causing the AD curve to shift to the ▼ left right . Part 5 Firms become pessimisticpessimistic about the future profitability of spending on factories and machinery. It would ▼ decrease increase current investment​ spending, causing the AD curve to shift to the ▼ right left .

6.42 Suppose that the time, in hours, required to repair a heat pump is a random variable X having a gamma distribution with parameters α = 2 and β =1/2. What is the probability that on the next service call (a) at most 1 hour will be required to repair the heat pump? (b) at least 2 hours will be required to repair the heat pump?

An oversupply of physicians in many urban regions contrasts with continuing problems of access in rural and inner-city areas. Why does the mal-distribution of physicians persist in spite of the number of physicians graduated? (2-3 slides)

Several years​ ago, the mean height of women 20 years of age or older was 63.763.7 inches. Suppose that a random sample of 4545 women who are 20 years of age or older today results in a mean height of 64.464.4 inches. ​(a) State the appropriate null and alternative hypotheses to assess whether women are taller today. ​(b) Suppose the​ P-value for this test is 0.090.09. Explain what this value represents. ​(c) Write a conclusion for this hypothesis test assuming an alphaαequals=0.050.05 level of significance.
