Question

Assume the sample is a random sample from a distribution that is reasonably normally distributed and we are doing inference for a sample mean. Find endpoints of a t-distribution with 0.005 beyond them in each tail if the sample has size n

Answer 1

The correct answer is "2.660".

Explanation:

Given that,

Sample size,

n = 61

t-distribution with,

t = 0.005

Now,

The degree of freedom will be:

=
`n-1`

=
`61-1`

=
`60`

hence,

⇒
`t,df=t_(0.005), 60`

`=2.660`
