Transcribed Image Text:A baseball team claims that the mean length of its games is more than 2.2 hours. State Ho and H₂ in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning.
State the null hypothesis in words and in symbols. Choose the correct answer below.
A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is 2.2 hours." The null hypothesis is expressed symbolically as, "Ho: μ = 2.2."
B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 2.2 hours." The null hypothesis is expressed symbolically as, "Ho: μ≤2.2."
C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 2.2 hours." The null hypothesis is expressed symbolically as, "Ho: μ ≥2.2."
D. The null hypothesis expressed in words is, "the mean length of a baseball team's games is not 2.2 hours." The null hypothesis is expressed symbolically as, "H₂: μ‡ 2.2."
State the alternative hypothesis in words and in symbols. Choose the correct answer below.
A. The alternative hypothesis expressed in words is, "the mean length of a baseball team's games is more than 2.2 hours." The alternative hypothesis is expressed symbolically as, "H₂: µ> 2.2."
B. The alternative hypothesis expressed in words is, "the mean length of a baseball team's games is 2.2 hours." The alternative hypothesis is expressed symbolically as, "H₂: μ = 2.2."
C. The alternative hypothesis expressed in words is, "the mean length of a baseball team's games is not 2.2 hours." The alternative hypothesis is expressed symbolically as, "H₂: μ‡2.2."
D. The alternative hypothesis expressed in words is, "the mean length of a baseball team's games is less than 2.2 hours." The alternative hypothesis is expressed symbolically as, "H₂: μ<2.2."
