Determine the null and alternative hypotheses. At one school, the average amount of time that tenth-graders spend watching television each week is 21.6 hours. The principal introduces a campaign to encourage the students to watch less television. One year later, the principal wants to perform a hypothesis test to determine whether the average amount of time spent watching television per week has decreased. Choose the best asnwer below: A. H0: μ = 21.6 hours HA: μ > 21.6 hours B. H0: μ = 21.6 hours HA: μ ≤ 21.6 hours C. H0: μ < 21.6 hours HA: μ > 21.6 hours D. H0: μ = 21.6 hours HA: μ < 21.6 hours E. H0: μ < 21.6 hours HA: μ = 21.6 hours
