Essay

Test the claim that $\mu _ { 1 } = \mu _ { 2 }$ Assume the two samples are random and independent. Use $\alpha$ = 0.05.
Population statistics: $\sigma _ { 1 } = 1.5 \text { and } \sigma _ { 2 } = 1.9$ Sample statisticsstatistics: $\overline { \mathrm { x } } 1 = 17 , \mathrm { n } _ { 1 } = 50 \text { and } \overline { \mathrm { x } } 2 = 15 , \mathrm { n } _ { 2 } = 60$
