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">
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." THe null hypothesis is expressed symbolically as, "H0: mu = 2.6"
C. The null hypothesis is expressed in words is "the mean length of a baseball's team's games is at least 2.6 hours. " the null hypothesis is expressed symbolically as, "H0: mu >= to 2.6"
state the alternative hypothesis in words and symbols. Choose the correct answer below.
A. The alternative hypothesis is expressed in words is, " the mean length of a baseball's team's games is more than 2.6 hours." THe alternative hypothesis is expressed symbolically as "Ha: mu > 2.6"
B. The alternative hypothesis is expressed in words is, "the mean length of a baseball's team's games is not 2.6 hours." The alternative hypothesis is expressed symbolically as "Ha: mu does not = 2.6"
C. The alternative hypothesis is expressed in words is, "the mean length of a baseball's team's games is 2.6 hours." THe alternative hypothesis is expressed symbolically as "Ha: mu = 2.6"
D. The alternative hypothesis expressed in words is, "the mean length of a baseball's team's games is less than 2.6 hours." THe alternative hypothesis is expressed symbolically as "Ha: mu <>
The hypothesis test is _______________ (right tailed, left tailed, or 2 tailed) because the _______________( alternative or null) hypothesis contains_______________ ( <,>, =, does not =, > or =to, < or="">
