QNT 275 FINAL EXAM.

QNT 275 FINAL EXAM.The regression model y = A + Bx + e is:  a nonlinear model  a deterministic model  a probabilistic model  an exact relationship The mean of a discrete random variable is the mean of its:  frequency distribution  percentage distribution  probability distribution  second and third quartiles The p-value is the:  smallest significance level at which the null hypothesis cannot be rejected  largest significance level at which the alternative hypothesis can be rejected  largest significance level at which the null hypothesis can be rejected  smallest significance level at which the null hypothesis can be rejected A quantitative variable is the only type of variable that can:  be graphed  have no intermediate values  assume numeric values for which arithmetic operations make sense  be used to prepare tables To make tests hypotheses about more than two population means, we use the:  analysis of variance distribution  normal distribution  t distribution  chi-square distribution
