The one-sample t statistic from a sample of n = 21 observations for the two-sided test of H0: μ = 60, Ha: μ ≠ 60 has the value t = –1.98. Based on this information: we would reject the null hypothesis at α = 0.05. All of the answers are correct. 0.025 < P-value < 0.05. we would reject the null hypothesis at α = 0.10
please explain Duppose a one-sample t test from a sample of n = 10 observations for the hypotheses Ho = 64 versus HA: +64 has the test statistic t = 3.21. The P-value for this test 15 a) greater than 0.02 b) between 0.0025 and 0.005 c) between 0.005 and 0.01 o uth d) between 0.01 and 0.02 e) not possible to be found for a negative test statistic. a mil
The one-sample t-statistic for a test of Hou = 42 versus H1:4 < 42 based on n = 15 observations has the value t= -1.343, where Ho and H are the null and alternative hypotheses, respectively. The sample size is denoted by n. Use this t-table to determine which two P-values bracket the P-value of the test. Report your answers in decimal form as listed in the t-table. K P-value of the test <
