1. Consider a random experiment of tossing a coin three times.
(a) Find the sample space S1if we wish to observe the exact sequences of heads and tails obtained.
(b) Find the sample space S2 if we wish to observe the number of heads in the three tosses.
2. Consider an experiment of drawing two cards at random from a bag containing four cards marked with the integers 1 through 4.
(a) Find the sample space S1 of the experiment if the first card is replaced before the second is drawn.
(b) Find the sample space S2 of the experiment if the first card is not replaced.
3. An experiment consists of rolling a die until a 6 is obtained.
(a) Find the sample space S1 if we are interested in all possibilities.
(b) Find the sample space S2 if we are interested in the number of throws needed to get a 6.
For a sample of n 4 weeks in which the daily temperature was extremely hot, the weekly average of hit-by-pitch players was M 15.5. Are players more likely to get hit by pitches during hot weeks?
On a December day, the probability of snow is .30. The probability of a "cold" day is .50. The probability of snow and "cold" weather is .15. Are snow and "cold" weather independent events?
For each of the following studies, say whether you would use a t test for dependent means or a t test for independent means.
A regional commuter airline selected a random sample of 25 flights and found that the correlation between the number of passengers and the total weight, in pounds, of luggage stored in the luggage compartment is 0.94.
What is the probability that the sample mean will be at least 1000? Do you need to use the central limit theorism to answer this question? explain.
