urther Practice QuestionsIn a popular weekly number game, a computer generates a combination of 6 different numbersthat can be any number from 1 to 15. A player places a stake for a choice of 6 different numbersfrom 1 to 15. He wins the game if he gets at least four of the numbers correct. Let X be thenumber of correct answers he has chosen.The distribution of X is illustrated in the table below.XP(X=x)01271511087152National Junior College3456Copy and complete the probability distribution table of X.Hence find the probability of winning the game.Given that a player has won the game, what is the probability that he wins with five numbers?(Give all the probabilities in terms of fractions in their lowest terms.)

The random variable X denotes the number of correct answers chosen by the player, when he chooses 6…

(07.04 LC) Mellie is conducting a test on mold spores on bread. She uses 6 slices of bread to compare two strains of mold. She applies one strain to the left side of the bread and one strain to the right side. She flips a coin to decide which strain goes on the right side of the bread. The mold spores that appear on each side are counted and she records them in a table. Bread Number of Spots for Strain 1 Number of Spots for Strain 2 1 30 19 2 21 17 3 15 15 4 13 12 5 6 9. 6 8 4 If Mellie is to perform an appropriate t-test to determine if there is a mean difference between the number of spots per piece of bread produced by the two strains, how many degrees of freedom should she use? 4 10 12 5
Directions: Answer each of the questions below and show work. Write down the computations you do. Ten FBI agents get together and compare their annual salaries. They are $45,000, $48,000, $49,000, $55,000, $63,000, $64,000, $65,000, $70,000, $75,000, $120,000. A. Compute the mean and median salaries. Be sure to show your work, and answer with a sentence. B. A data point that is very different from other data points is called an outlier. Which of these data points could be considered an outlier? What effect will this outlier have on the mean? C. Compute the mean again, but this time leave out the outlier. How does this number compare to the number you found in question 1?
