X=x; a=6
x^2 + x^2 = 6^2 (pythagorean theorem)
2x^2 = 36
x^2 = 36/2 = 18
x = square root of 18
x = 2.62 (to the nearest hundredth)

Answer:
D. Keep the significance level the same but collect more data
Step-by-step explanation:
The significance level is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. This significance level is usually established initially and does not need to be changed.
But, you can collect more data to gain a high standard of evidence for rejecting the null hypothesis. More data gives more evidence and leads to a result that is not attributed to chance, thus, proving that the result is statistically significant.
