- A recent public survey asked the following question. "Many people believe this playground is too small and in need of repair. Do you think the playground should be repaired and expanded even if that means raising the entrance fee to the park?" Describe two ways this question may lead to response bias. *** 00000 Select all that apply. A. The question mentions higher fees, which could make people reject improvements to the playground. B. The statement points out problems the respondent may not have noticed, and might lead them to feel they should agree. C. Not all people who visit the park may answer the question. D. Some people prefer smaller playgrounds. E. The survey is not limited to those who use the park. OF. The "many people" who believe this playground is too small and in need of repair are unlikely to take this survey because they already voiced their opinion.mplete: Chapter 8 Problem Set ack to Assignment Attempts 6. A sports analogy for hypothesis tests V In recent years, professional sports have incorporated the use of instant replay in order to dispute questionable calls by the referees. For example, in the National Basketball Association (NBA) a head coach is allowed to challenge the referees' decision on whether a shot was made before time expired in the game. In order for the referees to reverse their original decision, the instant replay must exhibit clear evidence to the contrary, Suppose the referees rule that the last shot of the game was made before the clock had expired. The coach of the opposing team believes that time ran out before the shot was made, and the coach challenges the referees' decision. The referees will review all available evidence (video taken from different camera angles) and make a decision. If there is evidence beyond a reasonable doubt that their original call was incorrect, the basket won't count.…A school psychologist is interested in the efficiency of administration for a new intelligence test for children. In the past, the Wechsler Intelligence Scale for Children (WISC) was used. Thirty sixth grade children are given the new test to see whether the old intelligence test or the new intelligence test is easier to administer. Is this a non-directional or directional hypothesis? How do you know?
- One attempt at the problem listed below. I need help with this problem.Let’s say your grandfather is 72 years old and your question is “Are my classmates’ grandfathers, on average, older than mine is”? What would be the null and alternative hypotheses in this scenario? Group of answer choices H0 : The population average age is less than 72. Ha : The population average age is greater than or equal to 72. The population average age is greater than 72. Ha : The population average age is less than 72. H0 : The population average age is equal to 72. Ha : The population average age is less than 72. H0 : The population average age is equal to 72. Ha : The population average age is greater than 72.Solve 2 and 3
- If you hypothesize that there is no difference between means, this means the alternative hypothesis is ??: ?1 = ?2 Determine whether the statement is true or false. If the statement is false, EXPLAIN why.The proportion of the population in favor of a particular law was about 66%. It is believed that the current proportion of the population in favor of the law has decreased. To assess this, you collect a sample of n=340 people and 197 indicate being in favor of the law. We wish to test the claim that the proportion of the population in favor of the law has decreased. Symbolically, the claim would be expressed as the alternative hypothesis: Ha:pH1: This is a homework question. I chose a Null Hypothesis that is equal to the Alternative because the professor is comparing the two formats. Is my reasoning correct? Would this be a directional question? A statistics professor is interested in finding out whether students perform better on exams if they are conducted in the classroom or online. He compares the final exam scores of his online statistics class with the exam scores of his in-person class. What is the null hypothesis for this scenario? Null Hypothesis: final exam scores in class = final exam scores online Alternative Hypothesis: final exam scores in class is NOT Equal to final exam scores online
- Describe a potential example of a "repeated measures t-tests" (see Ch. 11) that could be conducted within the social sciences, and list what you believe the outcome of the research would be for this study. No data or calculations are necessary whatsoever, but you should describe why you developed your chosen hypothesis (e.g., based on your own understanding of current research, real world observations, a wild guess, etc.).Solve the following problemPlease show a step-by-step solution. Please do not skip steps.
