Click the icon to view the upper critical values of the Student's t distribution. Determine the value(s) for -t -1,oh -10 Or #t-1.0/2 as appropriate for this test. (Round to three decimal places as needed. Use a comma to separate answers as needed.)) Calculate the decision statistic. X - Ho s/ Vn =(Round to three decimal places as needed.) State the conclusion of this test. the null hypothesis. There sufficient evidence that the yield is not equal to 10%
