Question A manager is interested in determining if the population standard deviation has dropped below 116. Based on a sample of n = 16 items selected randomly from the population, conduct the appropriate hypothesis test at a 0.10 significance level. The sample standard deviation is 109. \mathrm{H}_{0}: \sigma^{2} \geq 13,456 H_{A}: \sigma^{2}<13,456 \mathrm{H}_{0}: \sigma^{2}<13,456 H_{A}: \sigma^{2} \geq 13,456 \text { C. } \mathrm{H}_{0}: \sigma^{2}<116 \mathrm{H}_{\mathrm{A}}: \sigma^{2} \geq 116 H_{0}: \sigma^{2}=116 H_{A}: \sigma^{2} \neq 116
