An independent random sample is selected from an approximately normal population with an unknown standard deviation. Find the pvalue for the given sample size and test statistic. (Assume we're considering a two sided hypothesis tests in each question. Round your answers to three decimal places.) (a) n = 11, T: 1.72 :l Determine if the null hypothesis would be rejected at a = 0.05. O reject HO O fail to reject H0 (b) n = 17, T: 3.54 :l Determine if the null hypothesis would be rejected at at = 0.05. O reject HO O fail to reject H0 (c) n = 7, T: 0.73 :l Determine if the null hypothesis would be rejected at a: = 0.05. O reject HO O fail to reject H0 (d) n = 23, T: 2.23 :l
