EE Click the icon to view a t distribution table (13 046.22 15) x= 17.598 Sx = 16 01712719 n= 50 a. What is the number of degrees of freedom that should be used for finding the critical value t,2? df = (Type a whole number) b. Find the critical value t2 corresponding to a 95% confidence level. (Round to two decimal places as needed) c. Give a brief general description of the number of degrees of freedom OA The number of degrees of freedom for a collection of sample data is the number of unique, non-repeated sample values OB The number of degrees of freedom for a collection of sample data is the total number of sample values CThe number of dearees of freedom for a collection of sample data is the number of samole values that are determined after certain restrictions have been imposed on all data values Cick to select your answeriS).
