12. A census is an enumeration of all items from the population of interest under study. 13. If the linear relationship between the dependent and independent variables is positive, the scatterplot will show the data points on the (x, y) plane generally moving from the lower left corner to the upper right corner. 14. If x is a normal random variable with mean of 2 and standard deviation of 5, then P(x 7). 15. Let z, be a z score that is unknown but identifiable by position and area. If the area to the right of z, is 0.8849, the value of z, is -1.2. 16. In order to calculate the p-value associated with a test, it is necessary to know the level of significance ~ . 17. A two - tailed test of hypothesis for a population mean " with a significance level @ equal to .05 will have a critical value z equal to .475. 18. A statistics professor has claimed that her top student will average more than 98 points in the final exam. If you wish to test this claim, you would formulate the following null and alternative hypotheses: He : /=98 vg H,: u >98. 19. In conducting a hypothesis test for a correlation, the correct probability distribution to use is the F distribution. 20. In the generic formula of the confidence interval, the term ( critical value* standard error) is called margin of error. Point estimate +critical value* standard error
