In addition, please categorize them as being either: (i) a one-sided test to the right, (ii) a one-sided test to the left, or (iii) a two-sided test.

This is a one sided test to the left.

Part b

H0: µ = 255 Vs Ha: µ 255

This is a two sided test.

Part c

H0: µ 1.8 Vs Ha: µ>1.8

This is a one sided test to the right.

Part d

H0: µ 2 minutes 5.65 seconds Vs Ha: µ< 2 minutes 5.65 seconds

This is a one sided test to the left.

Part e
