The police suspect Ricky and make up an identity parade of five men with glasses. Ricky takes his place in the parade alongside four randomly chosen stooges. Two of the eyewitnesses identify Ricky and the third points to one of the stooges. What's the probability that Ricky would have been chosen by two of the three eyewitnesses if each witness had chosen completely at random? Solve this problem using the Binomial Probability Mass Function. (Tip: This problem will be easier to solve if you first find p, the probability of success on any one trial; in other words, the probability of a single eyewitness…
Yellow Sigatoka fungus has been identified to affect banana crops from a plantation in Kedah. To curb the spread of this fungal infestation, the Kedah agriculture department chose to use mineral oil sprayed on leaf surfaces of the affected banana plants. The previous average fungal spot observed was 500 spots/m?. The agriculture department is anticipating the mineral oil treatment will decrease fungal spots found on the banana leaf surface. Conduct all necessary steps starting from hypothesis statements to the conclusion.
An experiment was performed to determine whether different types of chocolate take different amounts of time to dissolve. Forty people were divided into five groups. Each group was assigned a certain type of chocolate. Each person dissolved one piece of chocolate, and the dissolve time (in seconds) was recorded. For comparison, each person in each group also dissolved one piece of butterscotch candy; these pieces were identical for all groups. The data, which include the group, the dissolve times for both chocolate and butterscotch, the difference between the dissolve times, and the ratio of the dissolve times, are presented in the following table. Note that the design is slightly unbalanced; group 3 has nine people and group 5 has only seven.

Is a new method of teaching reading to first graders (Method B) more effective than the method now in use (Method A)? You design a matched pairs experiment to answer this question. You form 20 pairs of first graders, with two children in each pair carefully matched by IQ, socioeconomic status, and reading-readiness score. You assign at random one student from each pair to Method A. The other student in the pair is taught by Method B. At the end of the first grade, all the children take a test to determine their reading skill. Assume that the higher the score on this test, the more proficient the student is at reading. Let p stand for the proportion of all possible matched pairs of children for which the child taught by Method B has the higher score. Your hypotheses are Ho: p = 0.5 (no difference in effectiveness) Ha:p > 0.5 (Method B is more effective) 12 = 0.6. 20 The result of your experiment is that Method B gave a higher score in 12 of the 20 pairs, or p If Ho is true, the 20 pairs…
