Essay

Test the claim thathat $\mu _ { 1 } \neq \mu _ { 2 }$ Assume the two samples are random and independent. Use $\alpha = 0.02$ Population statistics: $\sigma _ { 1 } = 0.76 \text { and } \sigma _ { 2 } = 0.51$ Sample statistics: $\overline { \mathrm { x } } 1 = 5.3 , \mathrm { n } _ { 1 } = 51 \text { and } \overline { \mathrm { x } } 2 = 5.7 , \mathrm { n } _ { 2 } = 38$
