According to the Carnegie unit system, the recommended number ofhours students should study per unit is 2. Are statistics students'study hours different from the recommended number of hours perunit? The data show the results of a survey of 11 statisticsstudents who were asked how many hours per unit they studied.Assume a normal distribution for the population. 3.9, 1.6, 2.6,3.8, 1.6, 2.5, 1.2, 2.4, 2, 0.8, 4 What can be concluded at the α =0.05 level of significance? For this study, we should use Select ananswer The null and alternative hypotheses would be: H 0 : ? Selectan answer H 1 : ? Select an answer The test statistic ? = (pleaseshow your answer to 3 decimal places.) The p-value = (Please showyour answer to 4 decimal places.) The p-value is ? α Based on this,we should Select an answer the null hypothesis. Thus, the finalconclusion is that ... The data suggest the populaton mean issignificantly different from 2 at α = 0.05, so there is sufficientevidence to conclude that the population mean study time per unitfor statistics students is different from 2. The data suggest thepopulation mean is not significantly different from 2 at α = 0.05,so there is sufficient evidence to conclude that the populationmean study time per unit for statistics students is equal to 2. Thedata suggest that the population mean study time per unit forstatistics students is not significantly different from 2 at α =0.05, so there is insufficient evidence to conclude that thepopulation mean study time per unit for statistics students isdifferent from 2. Interpret the p-value in the context of thestudy. If the population mean study time per unit for statisticsstudents is 2 and if you survey another 11 statistics students,then there would be a 25.84840864% chance that the sample mean forthese 11 statistics students would either be less than 1.6 orgreater than 2. There is a 25.84840864% chance that the populationmean study time per unit for statistics students is not equal to 2.There is a 25.84840864% chance of a Type I error. If the populationmean study time per unit for statistics students is 2 and if yousurvey another 11 statistics students then there would be a25.84840864% chance that the population mean would either be lessthan 1.6 or greater than 2. Interpret the level of significance inthe context of the study. There is a 5% chance that the populationmean study time per unit for statistics students is different from2. If the population mean study time per unit for statisticsstudents is 2 and if you survey another 11 statistics students,then there would be a 5% chance that we would end up falselyconcuding that the population mean study time per unit forstatistics students is different from 2. There is a 5% chance thatstudents just don't study at all so there is no point to thissurvey. If the population mean study time per unit for statisticsstudents is different from 2 and if you survey another 11statistics students, then there would be a 5% chance that we wouldend up falsely concuding that the population mean study time perunit for statistics students is equal to 2.
