- I need help with stats/2023 A baseball team claims that the mean length of its games is more than 2.6 hours. STate H0 and Ha in words and symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed or 2-tailed test. Explain your reasoning. State the null hypothesis in words and symbols. Choose the correct answer A. The null hypothesis is expressed in words is, "the mean length of a baseball's team's games is at most 2.6 hours." The null hypothesis is expressed symbolically as, H0: mu < or = to 2.6" B. The null hypothesis is expressed in words is, "the mean length of a baseball team's games is not 2.6 hours." The null hypothesis is expressed symbolically as, "H0: mu does not = 2.6" C. The null hypothesis is expressed in words is "the mean length of a baseball team's games is 2.6 hours."
