Perform the appropriate test to determine if there is statistically significant evidence (at 0.05 significance level) to show that, in fact, individuals sleep more on the weekend than during the week. (Let
μ1 correspond to workday and
μ2correspond to weekend, such that
μd = μ1 − μ2.)
State the null and alternative hypotheses.
H0: μ1 − μ2 = 0
H1: μ1 − μ2 > 0
H0: μ1 − μ2 = 0
H1: μ1 − μ2 ≠0
H0: μ1 − μ2 = 0
H1: μ1 − μ2 < 0
H0: μd = 0
H1: μd > 0
H0: μd = 0
H1: μd ≠0
H0: μd = 0
H1: μd < 0
Give the test statistic. (Round your answer to two decimal places.)
What can you conclude?
There is sufficient evidence at a significance level of 0.05 to suggest that individuals sleep more on the weekend than during the week. There is insufficient evidence at a significance level of 0.05 to suggest that individuals sleep more on the weekend than during the week.

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
