Student-t distribution table with a 99% confidence level and an n of 21 what is the critical value of t? In a left-tailed test and and an n of 29 what is the critical value of t with a 5% significance level? In a two tailed test with an n of 25 what are the critical values of t with a 1% significance level? In a left tailed test with a of two independent samples with an n of 16 in sample a and an n of 16 in sample b what is the critical value of t value of t with a 1% significance level? The calculated value for t is -1.501, The test is a left tailed test. The n is 20. What is the best estimate of the p value used the student t table. Please show solutions
