Tests the claim that # 2. Assume the samples are normally distributed, random and independent. of = o} 0.57; $2 0.66 =45.14; i = 44.85 n = 20; ng = 19 %3D a. Calculate the Standard Error s- = (use 3 decimals) b. Calculate the t-test statistic using the standard error from part a. t = (use 2 decimal places) c. What are the degrees of freedom? df %3D d. At a = 0.01, Use the distribution table to find the critical values for the rejection region te = + (use 4 decimal places) e. What is your conclusion? O Accept the alternative hypothesis and reject the claim O Accept the null hypothesis and support the claim O Reject the null hypothesis and support the claim O Fail to reject the null hypothesis and do not support the claim O Reject the alternative hypothesis and support the claim
