The national average SAT score is roughly 1500. We would like to see if the high school seniors who apply to Duke have higher than average SAT scores. We randomly sample 100 applicants' files and record their SAT scores. Which of the following is the correct set of hypotheses for this research question? Hint: think about how many samples we have data from. H0: μ = 1500; HA: μ ≠ 1500 H0: p = 1500; HA: p > 1500 H0: μ Duke= μ National; HA: μ Duke> μ National H0: x = 1500; HA: x > 1500 H0: μ = 1500; HA: μ > 1500

This is because nausea is common for people who have the flu. From past studies you know that about 33% of people who get the flu experience nausea. You collected data on 2371 patients who were taking Tamiflu to relieve symtoms of the flu, and found that 841 experienced nausea. Use a 0.01 significance level to test the claim that the percentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is greater than 33%. *.** ▸ Ezra Mill X HH Chief Be X V H₁: ?

Please use the five steps in hypothesis testing. (a) Meteorology: Storms Weatherwise is a magazine published by the American Meteorological Society. One issuegives a rating system used to classify Northeaster storms that frequently hit New England and can cause muchdamage near the ocean. A severe storm has an average peak wave height of μ=16.4 ft for waves hitting the shore. Suppose that a Northeaster is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 36 waves showed on average wave height of x̄=17.3 ft. Previous studies of severe storms indicate that σ=3.5 ft. . Does this information suggest that the storm is perhaps temporarily increasing above the severe rating? Use a=0.01
Data from 12 individuals was collected about their sleeping habits after meditation. These scores represent their sleep quality based on a 5 point Likert scale with higher numbers meaning better sleep quality. Use a μ = 2.4 SD = 0.75. Do these individuals differ in their sleep quality compared to the group average? Solve using the five steps of hypothesis testing. how to find Ho: M and HA: M (this is part of an assignment that can be completed as many times as necessary for 100% or whatever grade you choose, I'm just trying to understand how to do all of this because it's an online summer course and I'm very lost. Any help would be appreciated in learning to understand)
