GSS 2018 respondents were asked to rate their level of agreement to the statement, “Differences in income in America are too large.” Responses were measured on a 5-point scale: 1 = strongly agree, 2 = agree, 3 = neutral, 4 = disagree, and 5 = strongly disagree. Strong Democrats had an average score of 1.69 (s = 1.04, N = 86) while strong Republicans had an average score of 2.11 (s = 1.05, N = 67). The estimated standard error of the difference between meansis 0.17. What is the appropriate test statistic? Why? Test the null hypothesis with a one-tailed test (strong Democrats are more likely to agree with the statement than strong Republicans); α = .05. What do you conclude about the difference in attitudes for these two political groups? If you conducted a two-tailed test with α = .05, would your decision have been different?
In a recent poll six hundred adults were asked a series of questions about the state ofthe economy and their children’s future. One question was, “do you expect your children to have a better life than you have had, a worse life, or a life about the same asyours?” The responses showed 242 better, 310 worse, and 48 about the same. Use thesign test and a =.05 to determine whether there is a difference between the number ofadults who feel their children will have a better life compared to a worse life. What isyour conclusion?
Suppose that 75%75% of college students prefer pepperoni on their pizzas. You took a sample of ?=150n=150 at your college and found that 70%70% said they want pepperoni on their pizzas. You want to know if your college is different from the rest at the 10%10% level. What is the ?P‑value for this test?
Exercises 19: A researcher wants to know if a person would likely follow the smoking behavior of his/her father. A group of teenagers was randomly selected for this study. Out of the 19 smokers, 8 of them have smoker fathers while 11 have non-smoker fathers. On the other hand, 4 non- smokers have non-smoker fathers while 6 non- smokers have smoker fathers. At 5% level of significance, test whether a person's smoking behavior is the same as their fathers' ?
Support for the U.S. death penalty for convicted murderers was 63% in 2014 (Gallup poll results 2018). In a recent survey of 150 randomly selected U.S. adults, 75 said they were in favor of the death penalty for those convicted of murder. Does this sample appear to come from a population with a lower proportion in favor of the death penalty? d) Say that a = 0.05, what does this mean. Explain in the context of the problem. e) What would it mean to make a type II error? Explain in the context of this problem. f) Use a 0.05 significance level to test the claim. State your conclusion AND interpret your results.
What stats test should be used to solve the following? A positive psychologist compares whether levels of gratitude in a random sample of n = 50 students at her college (M = 40) differ from the mean of college students across the US (μ = 45). A sports psychologist tested the reaction time of 320 college athletes. She found their average reaction time in a controlled task to be .77 seconds (s = 21). She wondered if the college athletes had faster reactions times than college students on average, who typically reacted in 1.23 seconds. A school psychologist obtained a sample of 120 fourth-grade kids who engaged in remote learning only during the COVID-19 pandemic. She found their average anxiety score to be M = 168. He compared that mean to the average anxiety score of fourth-grade children before the pandemic, which was μ = 144, with a ?=12σ=12. Did the sample of kids engaged in remote learning have a significantly different level of anxiety?
i.20% of the response times are longer than how many minutes? iI.Find the IQR of the response times. Suppose that another “major city” claimed that its police force response times followed a normal model with a mean of 8 minutes. What is the SD of this model if 95% of the response times were at most 12 minutes? Show all steps in your solution.
The wrong alternative. One of your friends is testing the effect of drinking coffee on the duration of cold symptoms. The common cold lasts, on average, 6 days. Your friend starts with no expectations as to whether drinking coffee will have any effect on cold duration. After seeing the results of the experiment, in which the average cold duration was less than 6 days, your friend tests a one-sided alternative about the population mean cold duration when drinking coffee, H0: lcoffee = 6 На: Which gives a one-sided P value P = 0.0465. Explain why your friend should have used a two-sided hypothesis. Hcoffee < 6
The first pic is the question, since I’ve been receiving some incorrect answers from the tutors, I included an example problem in the second pic.
A researcher designed a study to test whether caffeine use enhanced performance time to run a 100 meter sprint. The participants (n=30) ran a 100 meter sprint before the consumption of caffeine on day 1 and then they ran another 100 meter sprint on the following day 2 after ingesting caffeine. The average time taken to run the 100 meter sprint on day 1 was (M1) and the average to run on day 2 after caffeine was (M2). The variance for this study was calculated to be (S2). Does caffeine use improve the running time in the 100 meter sprint (e.g., lower time)? Use all of the data provided to you below and test at an alpha of 0.05. M1 = 26.53M2 = 14.69S2 = 207.75n=30 a) state null and alternate hypothesis b) what is the critical value c) what is the obtained value d) conclusion
A political claims that 57% of voters in Madison County support his candidate. In a poll 400 randomly selected voters, 204 Of them support the strategist's candidate. At a=.05 is the political strategist's claim warranted? Yes or No and what is the Test Value?
