Statistical Tables (z, t, F and Chi-Square) Standard Normal Distribution Table (z 0. Which of the following tests would you use? Independent samples t-test O Chi-square test A paired t-test 2. If your test statistic for testing H1 : Ma > 0 at a = 0.025 is t = 1.843, which of the following is your conclusion? (Note: n = 16 and use the appropriate distribution table.) O df = 30, p-value 0.025 and the null hypothesis cannot be rejected. O df = 15, p-value 0 at a = 0.025 level of significance, which of the following is the critical value? (Note: n = 16 and use the appropriate distribution table.) 1.325 2.131 O 1.812A study was conducted to determine the relationship between sleep deprivation and the number of errors committed. The relationship between the 'number of hours without sleep' (x) and 'number of errors' (y) was studied in n = 12 physicians by using the least square regression. Suppose the following regression equation was obtained from this study: y = 6+0.52 x Use the above model to predict the number of errors for a person who has not slept for 20 hours. 10.4 errors 16.4 errors 20 errors 19.4 errors
