Jump to level 1A political campaign is interested in whether a geographic difference existed in supportfor raising the minimum wage in a certain state. Polls were conducted in the two largestcities in the state about raising the minimum wage. In city 1, a poll of 800 randomlyselected voters found that 390 supported raising the minimum wage. In city 2, a poll of1000 randomly selected voters found that 439 supported raising the minimum wage.What type of hypothesis test should be performed?

Random digit dialing telephone surveys used to exclude cell phone numbers. If the opinions of people who have only cell phones differ from those of people who have landline service, the poll results may not represent the entire adult population. The Pew Research Center interviewed separate random samples of cell-only and landline telephone users who were less than 30 years old. Here’s what the Pew survey found about how these people describe their political party affiliation. State the Null and Alternative Hypotheses.

A researcher wanted to know which local brewery had the best IPA. Each participant tried a sample from all three different breweries (Ore Dock, Black Rocks, and Barrel + Beam) and was asked to rate each one on a scale of 0-100. Use the six steps of hypothesis testing to determine if there was a significant effect of brewery on IPA popularity ratings. participant ore dock black rocks Barrel + Beam 1 40 30 53 2 42 45 65 3 30 38 64 4 37 32 43 5 23 28 38 What is the SS between?
Hawaii state law requires that businesses offer health insurance to employees that work at least 20 hours/week. An analyst at the state's Department of Labor wants to know whether the typical employee in Hawaii's hospitality industry works at least 20 hours/week. The analyst collects data from a random sample of 30 workers in the hospitality industry in Hawaii. The key variable is the number of hours worked per week. Is it a hypothesis test with one sample, two independent samples, or two dependent samples? Does it use means or proportions?

I can't figure out where I'm going wrong. I've probably been looking at it for too long now and I'm just missing something simple but I absolutely cannot figure it out. What I've come up with is that the GM is 40.53, the mean for OD is 34.4, BR is 34.6 and BB is 52.6. This has given me an SSbetween of 1092.1
-In a recent Gallup poll of 511 adults, 64% said that they were in favor of death penalty for a person convicted of murder. We want to use a 0.01 significance level to test the claim that the majority of adults are in favor of the death penalty for a person convicted of murder. a) Identify the null and alternative hypothesis. b) Find the value of the test statistic. c) Determine what we should conclude about the original claim.
