What’s the test statistic, and null hypothesis
right handedness is an individual’s preference to use the right hand as the dominant hand to perform various tasks. A random sample of 500 people were survey whether they are right handed. The researcher performed a hypothesis test to test the claim that the proportion of right handed people are more than 0.1. The population proportion of right-handed people is 0.10. The researcher concluded that there is enough evidence that the proportion of right handed people are more than 0.1. Identify whether the researcher's decision is a Type I error, Type II error, or correct decision.
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
Diagnostic tests of medical conditions have several results. The rest result can be positive or negative. A positive test (+) indicates the patient has the condition. A negative test (–) indicates the patient does not have the condition. Remember, a positive test does not prove the patient has the condition. Additional medical work may be required. Consider a random sample of 130 patients, some of whom have a medical condition and some of whom do not. Results of a new diagnostic test for the condition are shown. Condition Present Condition Absent Row Total Test Result + 109 21 130 Test Result – 21 49 70 Column Total 130 70 200 Assume that the sample is representative of the entire population. For a person selected at random, find P(getting test result – and condition absent). Round your answer to the nearest hundredth.

Perform a statistical analysis / test of hypothesis Suppose a researcher wants to see whether teaching students to read using a computer game gives better results than teaching with a tried-and-true phonics method. She randomly selects 20 students and puts them into 10 pairs according to their reading readiness level, age, IQ, and so on. She randomly selects one student from each pair to learn to read via the computer game, and the other learns to read using the phonics method. At the end of the study, each student takes the same reading test. The data are shown in the following table. Student Pair 1 2 3 4 5 6 7 8 9 10 Reading Score under Computer Method 85 80 95 87 78 82 57 69 73 99 Reading Score under phonics method 80 80 88 90 72 79 50 73 78 95 Test whether there is a significant difference between the computer method and the phonics method.
