For each setting indicate the appropriate statistical decision:

A) Ho: 120 vs Ha: > 120
    n = 16; alpha = 0.01 and t_test = 3.02
    ---Select--- Reject Ho Fail to reject Ho

B) Ho: 190 vs Ha: < 190
    n = 6; alpha = 0.05 and t_test = -1.43
    ---Select--- Reject Ho Fail to reject Ho

C) Ho: = 235 vs Ha: 235
    n = 9; alpha = 0.1 and t_test = -3.16
    ---Select--- Reject Ho Fail to reject Ho

D) Ho: 150 vs Ha: > 150
    n = 9; alpha = 0.025 and t_test = 3.35
    ---Select--- Reject Ho Fail to reject Ho

E) Ho: 175 vs Ha: < 175
    n = 11; alpha = 0.025 and t_test = -2.74
    ---Select--- Reject Ho Fail to reject Ho

F) Ho: = 250 vs Ha: 250
    n = 10; alpha = 0.05 and t_test = -1.70
    ---Select--- Reject Ho Fail to reject Ho
