1) In the data set below, what is the mean absolute deviation? 1) If the answer is a decimal, round it to the nearest tenth. (I) mean absolute deviation (MAD):

Why is it correct to say "a" normal distribution and "the" standard normal distribution? Describe the cases in which the different terms are used. Choose the correct answer below. A. "The" standard normal distribution is used to describe one specific normal distribution ( \( \mu=0, \sigma=1 \) ). "A" normal distribution is used to describe a normal distribution with any mean and standard deviation. B. "The" standard normal distribution is used to describe the normal distribution with any mean and standard deviation. "A" normal distribution is used to describe one specific normal distribution ( \( \mu=0, \sigma=1 \) ). C. "The" standard normal distribution is used in cases where all of the data values are known (population). "A" normal distribution is used in cases where only a portion of the data is known (sample). D. There is no difference between "A" and "The" normal distribution. The terms can be used interchangeably.
