Exploring Inferential Statistics and Their Discontents - Assignment mannequinAnswer Critical t 2.0687 at DF= 23 Critical t 2.1604 at DF= 13 He is more likely to make Type II error. 6. a) The test is two tailed. b) Ho u = 58 Ha u is NOT equal to 58 c) Calculate substantiateard deviation and mean for the sampling in the beginning then calculate t-value by using the following formula. t = (Xbar - u)* sqrt n/s n stand for the sample size s stand for the sample standard deviation Xbar stand for the sample mean u = 58 d) t-critical value Degrees of freedom = n - 1 = 14 - 1 = 13 level of signifi back toothce = alpha = 5% = 0.05 t-critical value = 2.145 e) Ho will be jilted if the computed t value is greater than the critical value f) 95% confidence interval for u depose be achieved by applying the subsequent formula. Sample mean +/- t critical value*s/sqrt n 8. a. X2 obtained = 4.74 b. df of the test = 1 c. x2 critical value = 3.84 d. This question can be done assuming it is on assessme nt of a hypothesis and using z test. capital of Mississippi (2012) Chapter 8, Pgs. 273-275 (even numbered exercises) 2. a. Statistical test a two-proportion t-interval b. Ho students listening to music while study have the mistakable scores as students not listening to music Ha students listening to music while studying have the worse scores than students not listening to music c. with Music Without Music Mean 6 7.75 Variance 1.142857143 2.214285714 Observations 8 8 Pearson Correlation equals -0.449013255 Hypothesized Mean Difference is Zero Degree of Freedom = 7 t Stat = -2.262609773 P(T
