A study to determine whether or not a football filled with helium traveled farther when kicked than one filled with air found that while the football filled with helium went, on average, farther than the one filled with air, the difference was not statistically significant. The response
a. is the number of kickers
b. is the distance that the football traveled
c. is the gas, air, or helium, with which the football is filled
d. does not exist without statistical significance
i cant figure out which one it is, i don't know what statistical signifigance is. but i think its d
any help??

d is right. Statistical significance means the measurement can lead to a conclusion.

thank you so much!
