Reference no: EM131137687

With reference to Example 3, use suitable statistical software to find the P-value that corresponds to t = -0.49, where t is a value of a random variable having the t distribution with 4 degrees of freedom. Use this P-value to rework the example.

Example 3

The specifications for a certain kind of ribbon call for a mean breaking strength of 185 pounds. If five pieces randomly selected from different rolls have breaking strengths of 171.6, 191.8, 178.3, 184.9, and 189.1 pounds, test the null hypothesis μ = 185 pounds against the alternative hypothesis μ
