Which four among the given statements are NOT true? • A hypothesis is a statement of belief or assumption about the values of sample parameters. [Select ] • In a trial comparing two diabetes drugs, the alternative hypothesis can claim that the fasting plasma glucose mean is significantly different between the patients with the experimental drug and the patients with the control drug. I Select] · A Type Il error occurs when one rejects the null hypothesis when it is true. [ Select] When the test statistic is in the critical region, then the null hypothesis must be rejected. ( Select ] • When the population standard deviation is unknown and the sample size is less than 20, t-test is more appropriate to use for testing hypotheses than Z-test. [ Select ] · For a right-tailed test of hypothesis, the null hypothesis should be rejected when the critical value is greater than the test statistic whether Z-test or t-test is used. [ Select] . The t-score corresponding to a two-tailed test with significance level of 10% and a sample size of 26 is 1.708. [ Select ] . Applying a left-tailed hypothesis test on a problem with a critical value of -1.782 and a test statistic of -1.951, the null hypothesis should be rejected. [ Select ]
