Population statistics: $\sigma _ { 1 } = 0.76 \text { and } \sigma _ { 2 } = 0.51$ Sample statisticsstatistics: $\overline { \mathrm { x } } 1 = 1.8 , \mathrm { n } _ { 1 } = 51 \text { and } \overline { \mathrm { x } } 2 = 2.2 , \mathrm { n } _ { 2 } = 38$

• A)Reject H₀ if the standardized test statistic is less than -2.33 or greater than 2.33.
• B)Reject H₀ if the standardized test statistic is less than -1.96 or greater than 1.96.
