Geographer louie intends to investigate whether there is a difference in how happy tourists are with their journey depending on where they are in the country (which part of the country). He divided the country into 5 parts: capital, south, east, west og north and selected 30 tourists at random from each area and asked (e. Chose 30 tourists in each part) and asked, "how enjoyable has your journey been in these areas on a scale of 0-10". louie is happy to have taken statistics in his time because there he learned to analyze data of this kind with analysis of variance. He started filling out an ANOVA table but could not complete it. The table can be seen below. It can be assumed that satisfaction follows a normal distribution and the distribution is similar in the five areas (e. Assume that happiness follows a normal distribution and that the variance is similar in the 5 parts). SS df Ms Between within 43.7 total 56.2 XXX 1.
