The sample mean is analogous to the center of mass in mechanics. - ANS True
The units associated with the sample standard deviation are the squared measurement units of
the original sample. - ANS False
If the sample variance is calculated from a sample of n observations, then it has n - 1 degrees of
freedom. - ANS True
The median of a sample is the most frequently occurring value in the sample. - ANS False
Discrete random variables take on values across a continuum. - ANS False
The binomial distribution arises from a series of Bernoulli trials. - ANS True
The Poisson distribution is widely used as a model of the number of events in an interval. -
