You wish to test the following claim (Ha\displaystyle {H}_{{a}}) at a significance level of α=0.10\displaystyle \alpha={0.10}.      

Ho:μ=75.4\displaystyle {H}_{{o}}:\mu={75.4}
Ha:μ>75.4\displaystyle {H}_{{a}}:\mu>{75.4}

You believe the population is normally distributed, but you do not know the standard deviation.
