The true mean hours of sleep a night of college students in the United States is 6.2 hours. Suppose you want to use a hypothesis test to determine whether the mean hours of sleep a night of BYU-Idaho students is higher than the national mean. Which of the following pairs of hypotheses is the most appropriate for addressing this question? H_o : mu = 6.2 qquad H_a : mu > 6.2 H_o : mu > 6.2 qquad H_a : mu = 6.2 H_o : mu = 6.2 qquad H_a : mu! = 6.2 H_o : mu! = 6.2 qquad H_a : mu = 6.2 H_o : mu = 6.2 qquad H_a : mu < 6.2 H_o : mu < 6.2 qquad H_a : mu = 6.2

H0: mu = 6.2 qquad Ha: mu > 6.2

Step-by-step explanation:

A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing. It is identified by the equality sign.

An alternate hypothesis is also a statement from a population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is identified by any of the inequality signs.
