Find the critical value in the t-distribution for a two-tailed hypothesis test in which α = .05 and df = 15 round your answer to the thousandth decimal place.

Step-by-step explanation:

The critical value in the t-distribution for a two-tailed hypothesis test is the t-value in the students's t-distribution table corresponding to the and df , where significance level and df = Degree of freedom.

We are given ,

Then,  

df = 15

Now , from the students's t-distribution table

The  critical value in the t-distribution for a two-tailed hypothesis test is

Hence, the required t-value =

d
