These are True or False Questions. Can you please write the number and T or F. Thanks 1. If the sample data are in the critical region with α = 0.05, then the same sample data would still be in the critical region if α were changed to 0.01 2. A z score near 0 indicates the sample mean is close to the population mean 3. If the sample mean falls in the critical region, the null hypothesis is rejected...
