Here's an example, and here is the problem. Try to solve it as best posible and make sure to label each step with its corresponding number.
MORE BENEFITS OF EATING ORGANIC Using data from a study, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eating organic potatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additional data from this study. In this case, we are testing where p, and p, represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and those eating conventional food, respectively. We have n₁ = n₂ = 500. Show all remaining details in the test, using a 5 % significance level. Effect of Organic Raisins After 20 Days After 20 days, 275 of the 500 fruit flies eating organic raisins are still alive, while 170 of the 500 eating conventional raisins are still alive. ¹Proportions approximated from information given in the paper. Part 1 Give the test statistic and the p-value. Round your answers to three decimal places. Ho: Po = Pc Ha: Po > Pe…
Part 1 You will be presented with several relationships and will be asked to write out the null and alternative hypotheses in the proper form. In this section you will: 1. Indicate the directionality of the relationship and what are being compared. Write the null hypothesis (remember, this is in terms of the population). 2. 3. Write the alternative hypothesis (remember, this is in terms of the samples). 1. A medical student is designing a clinical trial to test a new depression medication. The student believes the medication will reduce the severity of patient depression. 2. A researcher is running a study examining a new pilot training software using virtual reality technology. The researcher feels pilots trained using VR training program will perform differently than traditionally trained pilots during a simulated landing task. 3. A police officer believes younger drivers get ticketed more than older drivers. A researcher at a local university has decided to test the police officer's…

(1 point) According to a recent marketing campaign, 100 drinkers of either Diet Coke or Diet Pepsi participated in a blind taste test to see which of the drinks was their favorite. In one Pepsi television commercial, an anouncer states that "in recent blind taste tests, more than one half of the surveyed preferred Diet Pepsi over Diet Coke." Suppose that out of those 100, 42 preferred Diet Pepsi. Test the hypothesis, using a = 0.05 that more than half of all participants will select Diet Pepsi in a blind taste test by giving the following: (a) the test statistic (b) the critical z score
Which statement is accurate about the relationship between Populations and Samples? It is easier to test the entire population than to make inferences from a sample. If a sample is selected randomly from a population then it will be exactly equal to the population. Any difference between the population and the sample is known as sampling error All 3 statements are true
Answer each question plz also write a sentence for null and research/alternative hypothesis
