Question

Which of the following df values would make it so that the t Distribution looks most like the real Distribution of Sample Means (DSM)?

a- df = 8
b- df - 20
c-df = 30
d-df = 60

Answer 1

The df value that would make the t-distribution look most like the real distribution of sample means (DSM) is d- df = 60.

Step-by-step explanation:

The t-distribution is a probability distribution that is used to estimate population parameters when the sample size is small. The shape of the t-distribution depends on the degrees of freedom (df). As the df increases, the t-distribution becomes more and more similar to the standard normal distribution. Therefore, out of the given options, the df value that would make the t-distribution look most like the real distribution of sample means (DSM) is d- df = 60.
