What is the probability that a fast bowler chosen randomly from this group will have a maximum speed less than 145km/hr? A 0.24 B 0.34 C 0.67 D 0.76 Question 10 1 Point A population of part-time workers receive a mean of $110 per week with a standard deviation of $20. If a random sample of 25 people is taken, what is the probability their mean salary will be greater than $120 per week? A Approx 0.01 B Approx 0.95 C Approx 0.5 D Approx 0.99 E Approx 0.05
