In conducting research that looks at differences in populations, samples are used for numerous reasons. Using entire populations in a test is difficult, so various sampling techniques are applied. In situations in which the population variance is unknown, the Student t distribution is often used. To use this distribution, certain assumptions must be made. Which of the following statements is not correct?
a. 0 The t distribution is a family of distributions.
b. 0 It is a symmetrical, mound shape distribution.
c. 0 It is a continuous distribution.
d. 0 It has less spread than the standard normal distribution.
