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.
Which of the following statements are TRUE? There may be more than one correct answer; select all that are true. If Z is a standard normal random variable, P(Z <0.5) = 0. The interquartile range (IQR) of a normal distribution can be negative. The variance of a normal distribution cannot be negative. The 50th percentile of the standard normal distribution is 0. The 80th percentile of the standard normal distribution is positive.
Modified TRUE-FALSE. Write true if the statement is correct and if incorrect, change the underlined word to make the statement correct. IR spectra show absorption bands that enable to determine if certain functional groups are present in a molecule. IR spectra are expressed in wave number. Transmitted light have greater absorbance. (Emission) Absorption spectrum is the light of specific wavelength that is emitted when the atoms relax. When atoms absorb light of specific wavelength that causes the electrons to go...
