Use the calculator provided to solve the following problems. Consider a t distribution with 24 degrees of freedom. Compute P(t≥−1.72) Round your answer to at least three decimal places. Consider a t distribution with 18 degrees of freedom. Find the value of c such that P(-c. Round your answer to at least three decimal places. P(t≥−1.72)= c=
1. For a T distribution with 10 degrees of freedom, what is the probability P(T < -1.372)? 1. We consider a sample of 11 being used in a hypothesis test. In a two-sided hypothesis test where we reject if the value of |To| > Ta/2 is -2.05. Do you reject the null hypothesis in this case (explain why)? What is the p- value in this case (you may use a range for the p-value)? 2. This time a sample size...
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...
