Answer:
A. n = 22
Step-by-step explanation:
Hello!
The researcher conducted a one-sample t-tas with the following hypotheses:
H₀: μ = μ₀
H₁: μ ≠ μ₀
α:0.05
The one-sample t-test has "n-1" degrees of freedom and since the hypotheses are two-tailed you know that the rejection region will be divided into two tails with "α/2" for each tail. ± 
If α:0.05 then α/2:0.025 and 1-α/2= 0.975
Using the given sample sizes as a reference you look in the table for the corresponding DF for an accumulated probability of 0.975
For n = 22 
For n= 21 
For n= 20 
The correct answer is a) n= 22
I hope this helps!
