Write True if the statement is correct, otherwise write false. Thank you in advance

STATISTICS AND PROBABILITY WRITTEN WORKS Write TRUE if the statement is correct, otherwise write FALSE. (1 point each) Part A 1. A one-sample hypothesis test can involve two or more samples. 2. A two-tailed test with a = 0.05 has a z-critical values of 1 1.96.3. A left-tailed test with a = 0.01 has a z-critical values of -1.96. 4. t-test is used when the population o is unknown. 5. z-test is used when the population o is known. 6. Ho is rejected when the test statistic is in the rejection region. 7. z-test and t-test statistics have the same formula. 8. The significance level is equal to the area of the acceptance region. 9. If z = -1.43, 99% confidence, two-tailed test, then the x-z-value is rejected. 10. If u = 35,0 = 10, n = 48 and x = 40, the test statistic is z = -2.12
