Briefly explain what happens to the shape of the t-distribution as the degrees of freedom approach infinity.
Solution :
If we increase the degrees freedom to infinity the shape of the t-distribution closer to normal .

The shape of which distribution is not controlled by the degrees of freedom? F t Which of the following accurately represents characteristics of the x2 distribution? There may be more than one correct answer, select all that are correct. The degrees of freedom for a Chi-square test of independence are k-1. As the degrees of freedom increase, the critical value of the chi-square distribution becomes larger. | It can assume both negative and positive values. The Chi-square goodness-of-fit test is...

What are the degrees of freedom for Student's t distribution when the sample size is 25? d.f. = Use the Student's t distribution to find tc for a 0.95 confidence level when the sample is 25. (Round your answer to three decimal places.)
T or F? The student's-t distribution tends toward the Normal distribution with large degrees of freedom.
