Intro. to Stats – Test 2 Show working Consider the following data:                                                      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
