Answer:

D. 2.064

Step-by-step explanation:

Number of sample (n) = 25, degree of freedom = n - 1 = 25 - 1 = 24, significance level = 0.05

The critical t value corresponding to 24 degrees of freedom and 0.05 significance level is 2.064

Answer: correct option is B in which the critical value is 1.711

Step-by-step explanation:

The above question is a t distribution for single sample size. It is t distribution because the sample size is less than 30.

To get the critical value, find the degree of freedom(N-1),where N is the sample size and check at level of significant if 0.05. From the t distribution table, the critical value is 1.711
