(a) As the bond strength in a material increases we normally find that: the electrical conductivity decreases the electrical conductivity increases the melting point decreases the melting point increases The material becomes more metallic in character (b) In an intrinsic semiconductor: There are absolutely no impurities The electrical conductivity is only determined by thermal excitations The electrical conductivity is independent of the bandgap. There are equal numbers of free electrons and holes (Both electrons and holes will contribute significantly to...

Which of the following statements are TRUE? There may be more than one correct answer; select all that are true. A standard normal random variable cannot take on negative values. The normal distribution is symmetric about the mean mu. A normal distribution cannot have a negative mean. In a normal distribution, the mean and median are equal. If Z is a standard normal random variable, then P(Z > 41278) is very close to 0.
