The distance? If it is asking for the distance then its square root 313.
4/5,5/2 are the only ones that terminate
That both (along with the mean) help the data be described the data's spread, which can be the slope if only two points.
So,, there are 5 different flavors. A total of 180 people were asked. Hence, the hypothesis that there is no significant difference is that every flavor gets 180/5=36 flavors. x^2=

. In this case, mi is the proportion of the hypothesis, thus 36, n=180 and xi is the number of actual observations. Substituting the known quantities, we get that x^2=9. The degree of association is given by

. This yields around 0.10, much higher than our limit.
20/2.5 = 8
So 8 movies can be shown in 20 hours.
