Three new colors have been proposed for the jeep grand cherokee vehicle. they are silvered-blue, almond, and willow green. the null hypothesis for a goodness-of-fit test would be a. willow green is preferred over the other colors. c. any one color is preferred over the other colors. b. that there is no preference between the colors. d. impossible to determine.

A null hypothesis is a kind of hypothesis used in statistics. It proposes that, in a set of given observations, no statistical significance exists. The null hypothesis attempts to show that no variation exists between variables or that a single variable is no different than its mean. It is presumed to be true until statistical evidence nullifies it for an alternative hypothesis. 
So, for this problem, given that three new colors have been proposed for the jeep grand cherokee vehicle. those are silvered-blue, almond, and willow green, the null hypothesis is:

H0: b. that there is no preference between the colors.

Same length is comparing because it’s saying its the same and not different
