Q1,2

D Choose a FALSE statement regarding the t-distribution. The t distribution is based on the assumption that the population of interest is normal or nearly normal O There is not one t distribution, but rather a "family" of t distributions. O The t distribution has a greater spread than does the z distribution. As a result, the critical values of t for a given level of pinig in magnitude than the corresponding z critical values. O The higher the degree of confidence, the larger the sample required to give a certain precision O All t distributions have a mean of zero and a standard deviation of 1. Question 2 The mean SAT score for Division 1 student-athletes is 950 with a standard deviation of 220 If you select a cand sample of 100 of these students, what is the probability the sample mean is below 920?
