Explanation Given info: Claim: μ d > 0 The level of significance, α = 0.05 Sample statistics: d ¯ = 0.55 , s d = 0.99 and n = 28 Calculation: State the null and alternative hypotheses: Null hypothesis: H 0 : μ d = 0 Alternative hypothesis: H 1 : μ d > 0 (Claim) Critical values: Degrees of freedom: n − 1 = 28 − 1 = 27 Software Procedure: Step-by-step procedure to obtain the critical value using the MINITAB software: Choose Graph > Probability Distribution Plot choose View Probability > OK. From Distribution , choose ‘ t ’ distribution. In Degrees of freedom , enter 27 . Click the Shaded Area tab. Choose Probability value and Right Tail for the region of the curve to shade. Enter the Probability value as 0.05 . Click OK . Output using the MINITAB software is given below: From the output, the critical value is 1.703. Test statistic value: Software Procedure: Step-by-step procedure to obtain the test value using the MINITAB software: Choose Stat > Basic Statistics > 1-Sample t
