Nettet24. jul. 2024 · For example, if your t is 1.60 and your n is 7, you look in the row for df = 7 – 1 = 6. Across that row, you find your t lies between t -values 1.44 and 1.94. Go to the top of the columns containing the two t -values from Step 2. The right-tail (greater-than) probability for your t -value is somewhere between the two values at the top of ... NettetIf the one-tailed z-test is for the left tail, use -1.65 for the critical value. However, if the test is for the right tail, take advantage of the distribution’s symmetry and use +1.65. The z …

Netteta) Use the table to find the critical values from the t distribution that give an area of 0.05 in both the right tail and the left tail. Assume that the degrees of freedom is equal to 20. b) Find the probability: P (T > 2.870) assuming 10 degrees of freedom.
