K An education researcher claims that at most 4% of working college students are employed as teachers or teaching assistants. In a random sample of 600 working college students, 6% are employed as teachers or teaching assistants. At a=0.10, is there enough evidence to reject the researcher's claim? Complete parts (a) through (e) below. UI H₂:ps D. Ho: p≤ 0.04 Ha:p> 0.04 UI Ha: p= OE. Ho: P= H₂: p ... (b) Find the critical value(s) and identify the rejection region(s). Identify the critical value(s) for this test. UI H₂: p< OF. Ho: P< Ha: p² Zo (Round to two decimal places as needed. Use a comma to separate answers as needed.) T

Identifying the Method of Analysis Identify the method of analysis needed to answer the question. Indicate whether we should conduct a hypothesis test or find a confidence interval and also indicate whether the analysis will be done on a proportion, a mean, a difference in proportions, a difference in means, or a matched pairs difference in means. Use results collected at a supermarket to see whether there is a difference in the average amount of time customers have to wait in line between two different check-out cashiers.
