In problem that nine. We're going to be comparing a passenger ideal age in years with that given age group. And so this data shows six age groups and, ah, different ideal age. Is that they specifying And we're going to do a side by side box, but showing the six groups. So to do that, we have to select the deter the six age groups. And then you sat the box blood from thes battle. And as you can see here for the difference categories, the as you move from category two category, the ideal age increases. So that is what they display suggests that the display suggest that as you increase as you move from one category to the other, the age the ideal is increases. So this is the smallest for 18 to 24 the largest is for 65 plus. Now they're going to use this side, and then we're going to perform on analysis of variance to test the clean that they deal. Age is not the same for all age groups and they get to use offer. It's zero point 05 Okay, So to perform the analysis of brands, we go to data tub and data analysis and then select the and now another single factor. Then why deter? You have to select the palace, then make sure it's group by columns on the liberals in the fast room and I'll phase European 05 Ben with me. Make sure that we have output close to our deter. See, So then you press OK. And here the results for the analysis of lions. So we need to look at what decision has to be made based on these values. And we focused on the P value. So the P value is 1.5 substantially, probably getting 12 while there level of significance asked by 0.5 So this tells us that the P value is smaller than the level of significant Alfa, and in that case, we reject the night. But this is of and we are we because we can conclude that from the given sample, the mean ideal age is not the same for all age groups. So there are some differences from it group to a group when it comes to the ideal age. Then in part c of the question, we're going to be looking at what can cook conclusions we can draw from the results. Here. You find that when you're young, you tend tohave a smaller ideal age. And when you old, you have a large idea. So as you grow older, your ideal age seems to be also increasing. Then, in part d of the question, we're going to explain how this box plots drone demonstrate the results pond in Part B, where we tested the analysis of violence, using the analyst with various technique. So we see that ideal ages. The difference from age group is group things that means do not line up horizontally. Uh, if this means, or if this box puts oh well, it within one horizontal line, then would say that the ideal age I would not be affected by the each group.
