To test Ho: H = 50 versus H1: |

To test Ho: = 50 versus HI: < 50, a random sample of size n= 26 IS obtained from a popu anon that IS known to be normally distributed. Complete parts (a) through (d) below. Cl ck here to view the t-Distributlon Area In Right Tail (a) If x = 47.4 and s = 11.9, compute the test statistic. to (Round to three dec mal places as needed.) (b) If the researcher dec des to test this hypothesis at the 0.05 level of significance, determine the critical value(s). Although technology or a t-distributlon table can be used to find the critical value, In this problem use the t-distributlon table given. Critical Value: (Round to three decimal places. Use a comma to separate ansuvers as needed.)
