1. The school principal in a certain private junior high school claimed that 35% of all students are in favor of the new PE uniform. A research teacher asked his students to verify the claim. With this. 271 out 400 randomly selected students agreed to the new PE uniform. Using a - 0.10 level, is there enough evidence to conclude that the percentage of students who are in favor of the new PE uniform is different from 35%? a. What is the parameter in the problem? b. What is the claim in the problem?. C. Formulate the null hypothesis in symbol d. Formulate the alternative hypothesis in words. e. What tailed-test is applied in the problem? 2. To formulate alternative hypothesis concerning population proportion, there are three possible alternative hypotheses, and they are based on the wording of the question instructing you what to hypothesize. a. A problem with the expressions "smaller". "less", 'decreased", 'fewer". or "lower" is written in symbols as - b. A problem with the expressions "larger", "greater", "more". or "increased" is written in symbols as C. A problem with the expressions "different", "not equal to", or "changed" is written in symbols as 3. The test statistic used in testing hypothesis involving population proportion is whose formula is _ _ 4. A part of the sample or the proportion of individuals in a sample sharing a certain trait is known as - and is written in symbol as -. 5. Is it true that if the rejection region is two-tailed, a needs to be divided by 2 to be able to identify the rejection region? 6. If a problem does not indicate any term of direction, it is non-directional or two-tailed. Is it true or false? 7. The test statistic to be used in testing hypothesis involving population proportion is called 8. To be able to find q. subtract from - or simply -. 9. The decision is always based on the -- .- hypothesis. 10. After computing the test statistic in order to draw the conclusion, just remember the following: a. If the computed z-statistic (zcom) is > or
