The image is a statistical table titled "Area in Right Tail" which presents critical values for the t-distribution based on specific degrees of freedom (df) and tail probabilities (α). **Table Columns:**- The header row defines different levels of significance (α) from 0.25 to 0.0005.**Table Rows:**- The first column lists degrees of freedom (df) from 1 to 100.- Each subsequent column corresponds to a right-tail probability value (α) and presents the critical value for that specific combination of degrees of freedom and tail probability.**Explanation:**- Each cell in the table provides the t-value that marks the cutoff for the specified area under the right tail of the t-distribution, given the degrees of freedom and significance level.This table is used in hypothesis testing and confidence interval calculations, helping determine critical t-values for one-tailed tests. To test $ H_0: \mu = 60 $ versus $ H_1: \mu < 60 $, a random sample of size $ n = 26 $ is obtained from a population that is known to be normally distributed. Complete parts (a) through (d) below.Click here to view the t-Distribution Area in Right Tail.**(a)** If $ \bar{x} = 57.4 $ and $ s = 10.7 $, compute the test statistic.$ t_0 = $ (Round to three decimal places as needed.)**(b)** If the researcher decides to test this hypothesis at the $ \alpha = 0.05 $ level of significance, determine the critical value(s).

Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.10significance level to test for a difference between the measurements from the two arms. What can be concluded? Right arm 146 137 140 132 132 Left-arm 183 172 179 156 149 In this example, μd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the measurement from the right arm minus the measurement from the left arm. What are the null and alternative hypotheses for the hypothesis test? Identify the test statistic. Identify the P-value.
