8.8 In a greenhouse there are seedlings that are going to be transplanted later and that are being attacked by a discase. It has been decided to apply a treatment if more than 25% of the seedlings are affected. Assume that the number of seedlings is large enough that a Binomial model can be used and that the sample size is 16. a) Establish the hypothesis game if pertinent to the problem. b) Find a decision rule that defines a test with significance level a = 0.0795. c) Suppose that of the 16 plants examined, 9 are attacked by the discase. With 0.0795, would we decide to apply the treatment? d) What is the observed level of significance if 9 attacked plants are found? If 5 affected plants are found?

Molly works for a meat producer, and she needs to determine whether containers of ground beef have the correct fat content. She obtains a random sample of 120 containers of ground beef and finds that 84 percent have the correct fat content. Molly then conducts a hypothesis test of H0:p=0.80H0:p=0.80 versus Ha:p≠0.80Ha:p≠0.80 and calculates a test statistic of 1.10 with a pp-value of 0.273. Which of the following best represents the meaning of the pp-value? If the population proportion is 0.84, the probability of observing a sample proportion of 0.80 is 0.273. A If the population proportion is 0.84, the probability of observing a sample proportion of at least 0.04 less than 0.84 is 0.273. B If the population proportion is 0.80, the probability of observing a sample proportion within 0.04 of 0.80 is 0.273. C If the population proportion is 0.80, the probability of observing a sample proportion at least 0.04 greater than 0.80 is 0.273. D If the…

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)
