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!

Yes, you are correct. The correct answer is d. "does not exist without statistical significance." In this context, "statistical significance" refers to the level at which the difference between the two conditions (helium-filled football and air-filled football) is deemed unlikely to occur by chance. If the result is not statistically significant, it means that the observed difference is likely due to random variation rather than a true effect. Therefore, the study found that while the football filled with helium traveled farther on average, this difference was not significant, indicating that it could have occurred by chance.

Yes, you are correct. The response in this case is d) does not exist without statistical significance. To understand why, let me explain what statistical significance means.

In a study, statistical significance refers to the likelihood that the observed results are due to a real effect rather than mere random chance. It helps researchers determine if the observed differences between groups are meaningful and not just due to natural variation.

In this context, the study found that the football filled with helium traveled, on average, farther than the one filled with air. However, the difference in distance between the two types of footballs was not statistically significant. This means that the observed difference in distance could likely be due to random chance rather than a true effect of the helium filling.

Since the difference is not statistically significant, it implies that the response, or the thing being measured or studied, does not actually exist. In this case, it means that the difference in distance traveled by the footballs, when filled with helium or air, is not a real and meaningful difference.
