Find the value ta/2 for constructing a 95% confidence interval for 𝜇 if we draw a sample of size 15 from a normal population with 𝜎 unknown.
Question
Solution 1
To find the value of tα/2 for constructing a 95% confidence interval for 𝜇, we need to follow these steps:
Identify the degrees of freedom (df): The degrees of freedom for a sample is the sample size minus 1. In this case, df = 15 - 1 = 14.
