A baseball team claims that the mean length of its games is 2.8 hours. State Ho and H, in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasonin State the null hypothesis in words and in symbols. Choose the correct answer below. O A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is 2.8 hours." The nul hypothesis is expressed symbolically as, "Ho: u=2.8." O B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 2.8 hours." The null hypothesis is expressed symbolically as, "Ho: u22.8." OC. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 2.8 hours." The null hypothesis is expressed symbolically as, "Ho: us2.8." O D. The null hypothesis expressed in words is, "the mean length of a baseball team's games is more than 2.8 hours." The null hypothesis is expressed symbolically as, "Ho: u #2.8." State the alternative hypothesis in words and in symbols. Choose the correct answer below. O A. The alternative hypothesis expressed in words is, "the mean length of a baseball team's games is more than 2.8 hours." The altemative hypothesis is expressed symbolically as, "H,: u>2.8." O B. The alternative hypothesis expressed words is, "the mean length of a baseball team's games is 2.8 hours." The altemative hypothesis is expressed symbolically as, "H,: u=2.8." OC. The alternative hypothesis expressed in words is, "the mean length of a baseball team's games is not equal to 2.8 hours." The alternative hypothesis is expressed symbolically as, "H,: u#2.8." O D. The alternative hypothesis expressed in words is, "the mean length of a baseball team's games less than 2.8 hours." The alternative hypothesis is expressed symbolically as, "H,u<2.8." The hypothesis test is V because the V hypothesis oontains

Transcribed Image Text:A baseball team claims that the mean length of its games is 2.8 hours. State Ho and H, 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.
O A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is 2.8 hours." The null hypothesis is expressed symbolically as, "Ho: u= 2.8."
O B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 2.8 hours." The null hypothesis is expressed symbolically as, "Ho: u22.8."
OC. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 2.8 hours." The null hypothesis is expressed symbolically as, "Ho: uS2.8."
O D. The null hypothesis expressed in words is, "the mean length of a baseball team's games is more than 2.8 hours." The null hypothesis is expressed symbolically as, "Hn: u#2.8."
State the alternative hypothesis in words and in symbols. Choose the correct answer below.
O A. The alternative hypothesis expressed
words is, "the mean length of a baseball team's games
more than 2.8 hours." The altemative hypothesis is expressed symbolically as, "H: u>2.8."
O B. The alternative hypothesis expressed in words is, "the mean length of a baseball team's games is 2.8 hours." The alternative hypothesis is expressed symbolically as, "Hgi=2.8."
OC. The alternative hypothesis expressed in words is, "the mean length of a baseball team's games is not equal to 2.8 hours." The alternative hypothesis is expressed symbolically as, "H,: u#2.8."
O D. The alternative hypothesis expressed in words is, "the mean length of a baseball team's games is less than 2.8 hours." The alternative hypothesis is expressed symbolically as, "H, u<2.8."
The hypothesis test is
V because the
V hypothesis contains
