A 0.01 0.99 C 0.95 D 0.050/1 X A study hypothesised that the speed of fast bowlers differs between left- and right-handed bowlers. A sample of 12 left-handed bowlers had a mean x,= 131.5 kph and standard deviation Sleft = 15.5 kph while a sample of 8 right-handed bowlers had a mean x = 150.1 kph and standard deviation Sright = 8.1 kph. State appropriate null and alternative hypotheses. THIR: Hotleft F H right
