WebNo, the null hypothesis is that the population mean is equal to some specified value. When this is true (and the population is normal), the test statistic follows a t-distribution. The … WebThe t statistic is in the critical region, with a p-value LESS than 0.001, so we would decide to reject the null in our hypothesis testing. Based on C.I., the population difference of means (0) is not in the interval, therefore we can further confirm our hypothesis testing by rejecting the null hypothesis. Cohen’s d is a
