(a)Do these data provide evidence that the mean hunger rating differs for at least two of the treatments ("healthy" snack, "tasty" snack, no snack)? Test the relevant hypotheses using a significance level of 0.05.Find the test statistic. (Round your test statistic to two decimal places.)F = find the P-value. (Round your answer to four decimal places.)P-value = Do people feel hungrier after sampling a healthy food? The authors of a consumer research paper carried out a study toanswer this question. They randomly assigned volunteers into one of three groups. The people in the first group were askedto taste a snack that was described as a new health bar containing high levels of protein, vitamins, and fiber. The people inthe second group were asked to taste the same snack but were told it was a tasty chocolate bar with a raspberry center.After tasting the snack, participants were asked to rate their hunger level on a scale from 1 (not at all hungry) to 7 (veryhungry). The people in the third group were asked to rate their hunger but were not given a snack.The data in the table are consistent with summary quantities given in the paper (although the sample sizes in the actualstudy were larger).SampleMeanSampleStandardDeviationTreatmentHunger RatingGroupHealthy87474765.66671.7321Tasty142343.44441.5899No Snack3456.2444.33331.3229Overall mean = 4.48153.

Psychology experiments sometimes involve testing the ability of rats to navigate a maze. One researcher needs a maze that will take rats, on average, less than a minute to solve. The data below (image provided) gives the completion times for this maze for 20 randomly sampled rats. Will the maze fulfill the researcher’s time requirement? Use a significance level of ? = 0.05. What are the hypotheses. What are the test statistic and p-value. What is the full conclusion for this test in the context of the problem.

Report an appropriate hypothesis test for a positive linear relationship and use a 5% significance level. Explain the potential error in words, in context. In the answer options below I have used the phrase “a certain relationship” because I don’t want to give away exactly what type of relationship it is. Group of answer choices We would be accepting that there was a certain relationship between Sale amount and Tip when actually there wasn’t. We would not be accepting that there was a certain relationship between Sale amount and Tip when indeed there wasn’t. We would not be accepting that there was a certain relationship between Sale amount and Tip when actually there was.

As a psychiatrist you developed a test to measure happiness. Test the claim that the mean measure of happiness for females is equal to the mean measure of happiness for males. Use a significance level of .10. The data is given below. (although you could label group 1 to be male or female and get the same answer at the end, the middle would vary a little. So to match with me call group 1 females) (3 decimals) females males 9.6 7.6 8.9 6.9 6.7 9.6 6.3 5.8 7.1 9.4 6.1 7.3 C: μ1=μ2 HA;μ1#μ2 Ho: [Select] [Select] 8.4 7.9 9.7 P=[Select] 8.8 [Select] 7.8 Pis [Select] The data [Select] Critical value/s is [Select] + =-1.849 + (although you are rounding to 3 decimals this one ends up with only 2) the claim. +
