An answer to the question is as follows:

df= 49
test critical value = 2.01
The number of degrees of freedom for a collection of sample data is the number of sample values that are determined after certain restrictions have been imposed on all data values.

What is the number of degrees of freedom that should be used for finding the critical value t a/2?

a)

Generally, the equation for degrees of freedom is mathematically given as

df= n-1

Therefore

df= 50-1

df= 49

b)

For the critical value

Confidence interval= 95%

df= 49

Solving using a critical value calculator we have

test critical value = 2.01

c)

In conclusion, The number of degrees of freedom for a collection of sample data is the number of sample values that are determined after certain restrictions have been imposed on all data values. Option D is correct
