A study of young children was designed toincrease their intake of whole-grain, rather than regular-grain, snacks. At the end of the study, the 86children who participated in the study were presented with a choice between a regular-grain snackand a whole-grain alternative. The whole-grain alternative was chosen by 48 children. You want toexamine the possibility that the children are equally likely to choose each type of snack. (a) Formulate the null and alternative hypotheses for this setting.(b) Are the guidelines for using the large-sample significance test satisfied for testing this nullhypothesis? Explain your answer.(c) Perform the significance test and summarize your results in a short paragraph.
You conduct a poll of FIU students in order to determine the percentage of students (p) who agree with the statement “Hot-dogs are one of my favorite foods”. In your poll, you find that 80 out of 100 students agree. You conduct a two-sided hypothesis test where H0: p = 0.7, where p is the proportion of students whose favorite food is hot dogs. Which of the following statements are true: I. You reject the null hypothesis when α = 0.05 II. You reject the null hypothesis when α = 0.01 III. The test statistic (Z) equals Z = +1.5 Group of answer choices II only
A group of 250 patients was randomly split into two groups of 125 patients. The first group of 125 patients was given treatment A, and 72 of them improved their condition. The second group of 125 patients was given treatment B, and 60 of them improved their condition. Perform a hypothesis test to investigate whether there is evidence of a difference between the two treatments. What is the p-value of the test?

Imagine you are doing a Related-Samples t-test, and you are on Step Three of the hypothesis test. The sample of difference scores that you calculated is -5, -6, +2, -2, 0. What is the correct t-obtained? NOTE: The answer options also show many numbers that you calculate as part of the WORK for getting the t-obtained. VERY IMPORTANT HINT: The SS of these difference scores is 44.80.
According to the Minnesota Baccalaureate Psychomotor Skills Test (2008) your patient has significantly greater psychomotor skills than the average patient. Which of the following results would be appropriate to see with this finding? a-Z=1.36 (p=0.01) b-Z=5.67(p=0.08) c-Fail to reject the null d-Z= -1.98 (p=0.02) why is the answer a? and what is a trick to remember with p values? i understand that it is 0.05 or 5% chance of error
Can you help me determine the test statistic, the P-value, and the conclusion for this hypothesis test?
Imagine you are doing a Related-Samples t-test, and you are on Step Two of the hypothesis test. The sample of difference scores that you calculated is -1, -1, -3, +2, 0, -4. If you are doing the test with α = .01, and two tails, what would he correct t-critical be?
In a food preference experiment, 80 lizards were given the opportunity to choose to eat one of three different species of insects. The results showed that 33 of the lizards chose species A 12 chose species B, and 35 chose species C. They conducted a Chi-squared analysis to test for equal preference. What are the Null and Alternate hypotheses for this test? Clearly label your answers as HO or H1. (Do not use a numerical format. Both of your statements must be in sentence form, and say something about the lizards' preference in order to receive credit.) Edit View Insert Format Tools Table 12pt Paragraphv BI Y A
