A.The one hypothesis, H1 B.The null hypothesis, H0 C.The right hypothesis, H0 D.The alternative Hypothesis, H1Hello. Could anyone help me on this question? I have tried it four times and only one attempt left. What I am confusing is that some choice are not individual and variables. Like all young children, children who eat snack and cartoon characters. But if i leave them there, it shows me I am wrong. Pls help me on this and explanation would be appreciated.

Imagine you were given unlimited time and funding for these endeavors, what hypotheses within the realm of social science do you think would be great to explore? For instance, personally, I would love to test a number of hypotheses in the realm of education. As one example, I’d test the effect of class size on student outcomes. This could be examined with a hypothesis test (Ch. 8), since there is already plenty of established data regarding student grades in the current sized classrooms (which, for my courses is around 45 students). Thus, I could create a study in which a smaller group, perhaps n=10 students, takes the exact same course from me, and compare the mean grade for this treatment group to the population mean of all students in those past larger classrooms. This would, in theory, provide evidence as to whether or not smaller class sizes can increase student success. Unfortunately for me and for you, I don’t…Dating apps allow us to look a person's profile (or picture) and decide whether we'd like to date them (swipe right) or not (swipe left). Let us treat this like a hypothesis test, with the null hypothesis being that you don't want to date them. Then the swipe right decision is a positive result (rejecting the null) and the swipe left decision is a negative result (not rejecting the null). Suppose you think you're pretty good at deciding who you want to date, and you think that your sensitivity is 80% and your specificity is 66%. 4. If you go through the profiles of 200 people in a population where you expect 25% of the population to be dateable, how many times can you expect to swipe right? Hint: multiply the probability by the number of people to find out the expected number of swipes. 5. If instead the population had only 5% dateable individuals, how many times can you expect to swipe right? 6. Suppose you swipe right on a person from the 25% dateable population and go on a date.…
- ANOVA. Dr. Milgramm is conducting a patient satisfaction survey, rating how well her patients like her on a scale of 1-10. Her patients tend to fall into three categories: “Like a lot”, “like somewhat”, and “dislike a lot”. She believes that she might get different satisfaction scores from people in each group, but (because she's not great at numbers) she wants you to do an ANOVA to be sure. She has collected data from 12 patients (three equal groups) with the following results. Group 1) “Like a lot” Mean: 8 SS: 2 N: df: Group 2) “Like somewhat” Mean: 5 SS: 6 N: df: Group 3) “Dislike a lot” Mean: 2 SS: 4 N: df: Grand Mean: df Within-Group:__________ df Between-Groups:___________ Estimated Variance (S21) for Group 1: _______ Estimated Variance (S22) for Group 2: ___________ Estimated…a and b please thank youResources O Hint Inspired by the example about how background music influences choice of entrée at a restaurant, a statistics student decided to investigate other ways to influence a person's behavior. Using 60 volunteers, she randomly assigned 20 volunteers to get a "red" survey, 20 volunteers to get a "blue" survey, and 20 volunteers to get a control survey. The first three questions on each survey were the same, but the fourth and fifth questions were different. For example, the fourth question on the "red" survey was "When you think of the color red, what do you think about?" On the blue survey, the question replaced red with blue. On the control survey, the last two questions were not about color. As a reward, each volunteer was allowed to choose a chocolate candy in a red wrapper or a chocolate candy in a blue wrapper. Here are segmented bar graphs showing the results of the experiment. 100 Red candy Which of the following observations from the 80 Blue candy segmented bar graphs…
- Let’s say your grandfather is 72 years old and your question is “Are my classmates’ grandfathers, on average, older than mine is”? What would be the null and alternative hypotheses in this scenario? Group of answer choices H0 : The population average age is less than 72. Ha : The population average age is greater than or equal to 72. The population average age is greater than 72. Ha : The population average age is less than 72. H0 : The population average age is equal to 72. Ha : The population average age is less than 72. H0 : The population average age is equal to 72. Ha : The population average age is greater than 72.If you hypothesize that there is no difference between means, this means the alternative hypothesis is ??: ?1 = ?2 Determine whether the statement is true or false. If the statement is false, EXPLAIN why.Answer all parts
