Jse the t-distribution table to find the critical value(s) for the indicated alternative hypotheses, level of significance a, and sample sizes n, and ng. Assume that the samples are independent, normal, and random. Answer parts (a) and (b). H: H ), use "One Tail, a column with a positive sign two-tailed (#), use "Two Tails, a column with a negative and a positive sign. (a) Find the critical value assuming that the population variances are equal. Read the T Table when d.f. =n,+ ng -2 (Type an integer or decimal rounded to three decimal places as needed. Use a comma to separate answers as needed.) (b) Find the critical value assuming that the population variances are not equal. Read the T Table when d.f.= smaller of n-1 or n2 -1 (Type an integer or decimal rounded to three decimal places as needed. Use a comma to separate answers as needed.)

Question
Use the t-distribution table to find the critical value(s) for the indicated alternative hypotheses, level of significance a, and sample sizes n, and n2. Assume that the samples are independent, normal, and random. Answer parts (a) and (b). Ha: H1 <H2, a = 0.025, n, = 13, n2 = 11 Hint: left-tailed (<), use "One Tail, a column with a negative sign right-tailed (>), use "One Tail, a column with a positive sign two-tailed (#), use "Two Tails, a" column with a negative and a positive sign. (a) Find the critical value assuming that the population variances are equal. Read the T Table when d.f. = n,+ ng -2 (Type an integer or decimal rounded to three decimal places as needed. Use a comma to separate answers as needed.) (b) Find the critical value assuming that the population variances are not equal. Read the T Table when d.f.= smaller of n-1 or n2 -1 (Type an integer or decimal rounded to three decimal places as needed. Use a comma to separate answers as needed.)
