Intrо. tо Stаts – Test 2 Shоw working Consider the following dаtа: Condition Present Condition Absent Test Result + 150 10 Test Result - 25 70 One person is randomly selected from the group (a) Find Prob( Test Result - ) (b) Find Prob( Test Result + and Condition Absent ) For the data in question 1, find: (a) Prob( Condition Present | Test Result - ) (b) Prob( Test Result + | Condition Absent ) If P(A)=0.65, P(B)=0.1 and P(A or B)=0.3, find P(A and B). Are the events in question 3 mutually exclusive ? Explain. Laura has 7 Stats textbooks that she is going to place on a shelf. How many different arrangements of the books are possible if the order of the books on the shelf matters to Laura. A university advertises to fill 2 positions for Statistics teachers. 23 people apply. In how many ways can the positions be filled ? (a) Calculate 7P3 (b) Calculate 14C0 X 0 1 2 3 P(X) 0.7 0.05 ? 0.1 What does P(2) equal for this to be a probability distribution? What is the expected value of the probability distribution in question 8. a) For a binomial experiment, how many outcomes are possible for each trial ? b) In a binomial experiment, is it possible for the probability of success to change from one trial to the next ? Consider a binomial experiment with n=10 trials where the probability of success on a single trial is p=0.7. Find Prob(r=4). (a) What is the expected value of the binomial distribution in question 11 ? (b) What is the standard deviation of the binomial distribution in question 11 ? An unfair coin has prob(heads)=0.4. The coin is tossed. What is the prob. that the first tail occurs on the 7th toss ? ( Hint. Note that the word first is underlined ). A gale force wind occurs on average once every 60 hours on a mountain road. For an interval of 300 hours, what is the prob. that 3 gale force winds are experienced ? ( Hint, use a Poisson distribution. ) Cleo is a 65% basketball free throw shooter. She is interested in how many attempts it takes to make 4 baskets. What is the probability that it takes 12 attempts ? ( Hint. Note that the number of attempts is the variable in this question .) What is the mean and standard deviation of the Standard Normal distribution ? 17. What does a z-score represent ? 18. Consider a normal distribution with mean=20 and standard deviation=4 (a) Find a z value corresponding to an x value of 14 (b) Find the data value corresponding to a z value of 1.5 19. Find the area under the standard normal curve (a) To the right of z=1.52 (b) Between z=1.40 and z=2.03
