Eli wants to determine whether or not there is an association between gender and GPA among high school seniors in Ohio. He randomly selects 100 high school seniors at Amelia High School, a public school in southwest Ohio. He asks them to report their gender, as well as their current GPA. Out of these 100 students, 57 were female and 43 were male. The average GPA of the 57 female high school seniors was 3.4  What is the population in this study?

THIS CONTENT IS PROTECTED AND MAY NOT BE SHARED, UPLOADED, SOLD, OR DISTRIBUTED Problem 5. – 10 Points total A power semiconductor device consists of a region doped with Boron atoms such that the concentration of holes is p0 = x 1017 cm-3. The device dissipates power which generates heat, thus heating the silicon crystal to a temperature of T = °K. Use: m*n = 1.08 m0, m*p = 0.56 m0, Egap = 1.12 eV = Ec with Ev = 0 as the reference, and m0 is the free electron mass = 9.11 x 10-31 kg. Assume Boltzmann statistics applies and do the following:   (a) Find the intrinsic Fermi level EFi                                                             2 pts (b) Find the intrinsic carrier concentration ni = pi                                      2 pts (c) Find EF – Ev                                                                                               2 pts (d) Find Ec – EF                                                                                               2 pts (e) Calculate the respective minority carrier concentrations n0 or p0      2 pts
