AP Statistics ? Chapter 14 Practice Test: The Chi-Square Distributions Part II, Free Response ? Show all work and communicate completely and clearly. 1. Computer software generated 500 random numbers that should look like they are from the uniform distribution on the interval 0 to 1. They are categorized into five groups: (1) less than or equal to 0.2 (2) greater than 0.2 and less than or equal to 0.4, (3) greater than 0.4 and less than or equal to 0.6, (4) greater than 0.6 and less than or equal to 0.8, and (5) greater than 0.8. The counts in the five groups are 113, 95, 108, 99, and 85, respectively. a. The probabilities for these five intervals are all the same. What is this probability?

?? Q 2 ? Stain the inner central pith sample in the same way. Draw a few of the cells that characterize what you see from each slide. Give a heading to each in the space below and label as many of the cell structures/organelles as you can find - can you see a nucleus? What might this indicate about the cell and gene expression, mRNA creation? Inner (green, stained) Outer (green, stained) ? 4) Complete steps 1-3 for the ripe and overripe banana samples. Draw your diagrams for each STAINED sample in the spaces below, BUT only do counts for ?outer cells.? ? Ripe Banana - With iodine stain INNER OUTER ? Overripe Banana - With iodine stain.

Research

Research the meaning of null hypothesis. Describe how and why it is used in experimental design. Properly cite your reference. In statistical inference of observed data of a scientific experiment, the null hypothesis refers to a general or default position: that there is no relationship between two measured phenomena,[1] or that a potential medical treatment has no effect.[2] Rejecting or disproving the null hypothesis ? and thus concluding that there are grounds for believing that there is a relationship between two phenomena or that a potential treatment has a measurable effect ? is a central task in the modern practice of science, and gives a precise sense in which a claim is capable of being proven false.

Chapter Two What is science? Science: ? is a methodical, logical process for producing knowledge about natural phenomena ? a cumulative body of knowledge ----- Table 2.1 : Basic Principles of Science (7) Science depends on skepticism and accuracy ? Ideally scientists are skeptical and un biased. ? Scientist strive for ? Accuracy- correctness of measurement ? Reproducibility- Repeatability of result : Repeating studies or tests is called replication Deductive and inductive reasoning ? Deductive reasoning- logical reasoning from general to specific ? Inductive reasoning- reasoning from many observations to produce a general rule ? It is also important to recognize the role of insight, creativity, aesthetics, and luck in research

Against All Odds Program 1 Quiz ?What is Statistics?? Name ________________ 1. Dr. Amabile is a _______________ as well as a psychologist. The secret of success is using _______________ to check each step of the operation. Consumer trials stick to a precise script so the results can be compared _______________. Any _______________ due to order of presentation gets cancelled out in the second round. There?s one more essential step, ________________________ the whole package in selected cities and measuring the response. Without these statistical analyses, we would never really be sure whether or not two things are ___________________ different or not, we?d just be guessing.
