A research center claims that 30% of adults in a certain country would travel into space on a commercial flight if they could afford it. In a random sample of 800 adults in that country, 34% say that they would travel into space on a commercial flight if they could afford it. At α=0.05, is there enough evidence to reject the research center's claim? Complete parts (a) through (d) below. (a) Identify the claim and state H0 and Ha. Let p be the population proportion of successes, where success is an adult in the country who would travel into space on a commercial flight if they could afford it. State H0 and Ha. Select the correct choice below and fill in the answer boxes to complete your choice. b) Use technology to find the P-value. Identify the standardized test statistic. Identify the P-value. (c) Decide whether to reject or fail to reject the null hypothesis and (d) interpret the decision in the context of the original claim.
A sample is selected from a population with population mean = 50 After a treatment is administered to the individuals in the sample, the mean is found to be M = 55 and the variance is s ^ 2 = 64 a. If the sample has n = 36 scores, then conduct the four steps of hypothesis testing to evaluate the significance of the treatment effect and calculate Cohen's d to measure the size of the treatment effectUse a two-tailed test with alpha fevel = .05
A researcher is interested in studying the difference in the average level of anxiety among college students who are in their first semester of college compared to students who are in their final semester of college. The researcher has a sample of 62 students in their first semester and 60 students in their final semester and conducts a two-sample t-test (two-tailed, alpha = .05). The researcher finds the following: 1. Students in their first semester of college (group 1) have an average anxiety score of 1.8. 2. Students in their final semester of college (group 2) have an average anxiety score of 2.8. 3. The standard error of the mean difference between students in their first semester and final semester (i.e., the se) is .20. What are the degrees of freedom for this test? Enter your answer as a whole number with no decimal places (i.e., 10, not 10.1, not 10.10).
A random sample of 54 students from Cabrillo College are selected from a normal population with mu equal to 20 and sigma equal to 5. After a treatment is administered to the students, the researcher calculated the sample mean to be 21. Is there enough evidence to conclude that the treatment had an effect at the 5% significance level? In step three, can we use the Critical Value Method? (a)Don't know (b)Cannot Determine (c)No (d)Yes
