- Present the five-step model, testing your hypothesis at the 0.05 level.A foreign car manufacturer advertises that its newest model, the Bullet, rarely stops at gas stations. In fact, they claimed that its EPA rating for highway driving is at least 32.5 mpg. However, the results of a recent independent study determined the mpg for 50 identical models of the Bullet, with these results: n = 50, x= 30.4 mpg, and s = 5.3 mpg.This report failed to offer any conclusion, and you have been asked to interpret these results by someone who has always felt that the 32.5 figure is too high. What would be your conclusion using a significance level of 5%?Z = 1.645Genesis wants to invest his money in a fast food restaurant.

Formulate one null (H0) and one alternative (H1) hypothesis.I need help with this question, my teacher is asking us to disprove the friend's idea by doing an experiment and I have no idea on how to do it :(Infants, even newborns, prefer to look at attractive faces compared to less attractive faces (Slater, et al., 1998). In the study, infants from 1 to 6 days old were shown two photographs of women’s faces. Previously, a group of adults had rated one of the faces as significantly more attractive than the other. The babies were positioned in front of a screen on which the photographs were presented. The pair of faces remained on the screen until the baby accumulated a total of 20 seconds of looking at one or the other. The number of seconds looking at the attractive face was recorded for each infant. Suppose that the study used a sample of n = 9 infants and the data produced an average of M = 13 for the attractive face with an estimated standard error sM= 1 (SS = 72). If there were no preference, the 20 seconds should be divided equally between the two photographs. Note that all the available information comes from the sample. Specifically, we do not know the population mean or the…

About 20% of the teen population vapes. If you learn that a teen has pneumonia, what is the likely hood that they vape?Dr. Aukuculus is exploring the effects of bluelight on college students' sleep schedule. He uses 16 students to test his theory, 8 using bluelight 30 minutes before they go to bed and 8 using no bluelight 30 minutes before bed. He believes that students who use the bluelight will have struggles falling asleep, compared to students who do not use the bluelight. He has collected data to support his hypothesis, the higher the number the longer it takes the student to fall asleep, and the lower the number the shorter it takes the student to fall asleep. Values are the number of minutes. Bluelight No Bluelight 14 14 22 13 30 12 25 12 23 20 16 17 23 10 30 13 Please calculate the test statistic and pvalue. What can be concluded? Support your answer.
