Answer:
Since the null hypothesis is true, finding the significance is a type I error.
The probability of the year I error = level of significance = 0.05.
so, the number of tests that will be incorrectly found significant is computed as follow: 0.05 * 100 = 5
Therefore, 5 tests will be incorrectly found significant given that the null hypothesis is true.
The answer should be 1. Keep in mind that all cubic curves will always have at least 1 real zero. The embedded image is a graph of y=(x+8)³+9
The second answer should be y=x

-6x

+6x

-6x+5 (the last answer choice), as seen by the second image.
