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.
The square root of 245 to the nearest hundredths place is 15.65.
