Solution :

The null and alternative hypothesis is given by

$H_0: \mu = 11$

$H_a: \mu \ne 11$

Assume that the level of significance, α = 0.05

The t-test statistics is, t = 1.484

Degree of freedom :

df = n - 1

   = 14 - 1

   = 13

The P-value is given by

P-value = 2P (T>|t|)

            = 2P(T>|1.484|)

            = 2P(T>1.484)

            = 2(=T.DIST.RT(1.484,13))

            = 0.05

Answer:

Step-by-step explanation:

Hey, um, I dont know if ur still doing the whole stop the hackers thing, but there's this one user, echo2155, that I've seen post a link (or a bunch, not sure). I don't remember what they said, because their answer got deleted. I just figured I'd tell u, because I want to stop it too. It's really anoying when people do it on my questions becuz they use up a question and other people can't answer. I report as many as I can, but there's so many people that do it. I hope this is what ur looking for, bye!
