Let \( \mu_{1} \) be the mean battery life for WiFi-only tablets and \( \mu_{2} \) be the mean battery life for \( 3 \mathrm{G} / 4 \mathrm{Gi} \) wiFi tablets. Determine the hypotheses. Choose the correct answer below. A. \( \mathrm{H}_{0}: \mu_{1} \geq \mu_{2} \) B. \( \mathrm{H}_{0}: \mu_{1}=\mu_{2} \) \( H_{1}: \mu_{1}<\mu_{2} \) \( \mathrm{H}_{1}: \mu_{1} \neq \mu_{2} \) L. \( \mathrm{H}_{\mathrm{D}}=\mu_{1} \neq \mu_{2} \) D. \( \mathrm{H}_{0}: \mu_{1} \leq \mu_{2} \) \( H_{1}: \mu_{1}=\mu_{2} \) \( H_{1}: \mu_{1}>\mu_{2} \) Find the test statistic.
