Justify your answer. Circle the most stable moleculels. Even though the sample size is small (3) the statistic comes from a normal distribution. The dynamic range of the lower histogram is defined from lowest nonzero gray level lmin to mean value mi, whereas the dynamic range of upper histogram ranges from mi + 1 to highest nonzero gray level value lmax. Thus, any sample size will produce a normal distribution for EMBED Equation.DSMT36 . D. a probability that is equal to 1-p-vale If you have three-dimensional graphing software,graph the function with a domain and viewpoint that reveal all theimportant aspects of the function. E.
