The data supports the claim that college students get less sleep than the general population.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 7 hours
Sample mean, = 6.87 hours
Sample size, n = 145
Alpha, α = 0.10
Sample standard deviation, s = 0.55 hours
a) First, we design the null and the alternate hypothesis
We use One-tailed t(left tailed) test to perform this hypothesis.
b) Formula:
Putting all the values, we have
c) Now,
d) Since,
We fail to accept the null hypothesis and reject it.
e) Thus, the data supports the claim that college students get less sleep than the general population.
