What sample size would you need in order to have a 94% confidence interval that is 8% wide? Do this calculation twice: once with the previous sample proportion, then again using the "safe" sample proportion. Comment on how these two answers compare tp each other.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
