If you randomly select one butterfly from the table above, what is the probability of selecting a red butterfly or one collected in spring? 2. If you randomly select one butterfly collected in spring, one butterfly collected in summer, and one butterfly collected in autumn, what is the probability of selecting all yellow butterflies? 3. Determine the appropriate approach to conduct a hypothesis test for this claim: Fewer than 5% of patients experience negative treatment effects. Sample data: Of 500 randomly selected patients, 2.2% experience negative treatment effects. A) Use the normal distribution. B) Use the Student t distribution. C) Use the chi-square distribution.

MTH 231 Week 1 DQ 1 and DQ 2 FOR MORE CLASSES VISIT Week 1 DQ 1 Select the commodity of your best interest by ticking the box. You should get the data table thru clicking “retrieve” button at the end part of the list. ( You may use a commodity which is not explained in the class) Select the data among the month from 10 to 11 years as depicted below. Paste it to your clipboard using your mouse. Use only the numbers, not the month. Apply statdisk and paste it on statdisk. You are then required to select which column to be used. You have to choose column 1.

MTH 231 Week 1 Individual Assignment Populations FOR MORE CLASSES VISIT Resources: Ch. 1 of the text, the Internet, and the University Library Consider how life sciences researchers collect information from samples to learn about populations. Write a 700- to 1,050-word paper about sampling from populations. Include the following information: Define population and describe the characteristics of a population. Define sample and describe the characteristics of a sample. Compare samples and populations and explain how the concepts are related. Provide examples to illustrate your arguments.

MTH 231 Week 2 DQ 1 and DQ 2 FOR MORE CLASSES VISIT Week 2 DQ 1 Suppose a birdwatcher averages spotting 0.3 rare finches every day during the two hours allotted for watching. This means that the birdwatcher spots, on average, three rare finches every 10 days. The average is based on considerable experience. Over a given 10-day period, the birdwatcher sees zero rare finches in five days, and on the sixth day, the birdwatcher declares, “I’m due to see a rare finch today.” Assume that the environmental conditions are reasonably constant with no seasonal migratory issues involved. There is reasonably consistent weather and there are no confounding (lurking, unseen) variables involved. There is, however, a flaw in the birdwatcher’s statement. What is the error and why is it wrong?

MTH 231 Week 3 DQ 1 and DQ 2 FOR MORE CLASSES VISIT Week 3 DQ 1 What are the characteristics of a normal probability distribution function (pdf). What is the standard normal pdf? How is it related to the normal pdf and why is it useful? Explain the Empirical Rule? Is it used for rough estimates or precise calculations? Briefly tell how to use Table A-2 in the Appendix of our text to calculate z- values (Triola, 2006). How is area under the standard normal curve related to probability? Is the table arranged so that probability is cumulative from the left or from the right?
