What is the critical value t' for constructing a 90% confidence interval for a mean from a sample size of
Oksana_A [137]

Answer:

t^* = 1.740

Explanation:

Given

n = 18 --- sample

CI= 90\% --- confidence interval

Required

Determine the critical value

Start by calculating the degrees of freedom (df)

df = n - 1

df = 18 - 1

df = 17

Next, calculate the significance level

\alpha = \frac{1 - CI}{2}

This gives:

\alpha = \frac{1 - 90\%}{2}

Express percentage as decimal

\alpha = \frac{1 - 0.90}{2}

\alpha = \frac{0.10}{2}

\alpha = 0.05

Next, we look at the t table at

df = 17

and

\alpha = 0.05

We have the critical value to be:

t^* = 1.740
