A random sample of six steel beams has mean compressive strength of 58.392 psi (pounds per square inch) with a standard deviation of s = 648 psi. Test the null hypothesis H, = u = 58,000 psi against the alternative hypothesis H; H> 58,000 psi at 5% level of significance (value for I at 5 degree of freedom and 5% significance level is 2.0157). Here I denotes the population mean (A.MIE, Summer 2000)

Question
A random sample of six steel beams has mean compressive strength of 58.392 psi (pounds per
square inch) with a standard deviation of s = 648 psi. Test the null hypothesis
H, = u = 58,000 psi against the alternative hypothesis H; H> 58,000 psi at 5% level of significance
(value for I at 5 degree of freedom and 5% significance level is 2.0157). Here I denotes the population
mean
(A.MIE, Summer 2000)
