Question 7 1 Point Imagine you draw samples of 100 cases from a population with a mean of 57 and a standard deviation of 20. What are the mean [mi and the standard error (s) for the sampling distribution? m-57, sem-2 m=57, sem=200 m=57, sem=20 D m=57, sem-4 Question 8 1 Point You draw successive random samples of nine participants from a population. If the population has a mean of 12 and a standard deviation of 6, the standard deviation off the sampling distribution of the sample mean is (C D Cannot be determined Question 9 1 Point In professional cricket one of the generally accepted requirements for a bowler to be considered express is that they have to be able to bowl above 145 km/hr. With this In mind, a contingent of pace bowlers had a bowling competition and measured the speed of their quickest ball. They found that the overall mean was 138.9km/hr with a standard deviation of 8.6 km/hr. What is the probability that a II fast bowlers chosen randomly from this group will have a mean maximum speed greater than 145kum/hr? Approx 0.25 (25#) Approx 0.01 (1#4) Approx 0.99 (99%) Approx 0.75 (75%) Question 10 1 Point A population of 20-29 your-old males has a mean salary of $29,321 with a standard deviation of $2, 120. If a sample off 100 men is taken, what is the probability their mean salaries will be less than $29,000? Approx.. 0.22 (or 22%) B Approx 0.93 (or 93%) Approx.. 0.50 (or S0%) Approx 0.72 (or 72%) E Approx. 0.07 (or 7%)
