Let X denote the voltage at the output of a microphone, and suppose that X has a uniform distribution on the interval from −1 to
1. The voltage is processed by a "hard limiter" with cutoff values −0.5 and 0.5, so the limiter output is a random variable Y related to X by Y = X if |X| ≤ 0.5, Y = 0.5 if X > 0.5, and Y = −0.5 if X < −0.5.

Answer:
So then our significance level is and we need to remember these two conditions:
1) If the p value we have enough evidence to reject the null hypothesis at the significance level given
2) If the p value we have enough evidence to FAIL reject the null hypothesis at the significance level given
And baed on the options we see that the only possibility would be:
d. 0.015
Step-by-step explanation:
We want to know for which value we would REJECT the null hypothesis.

Answer:
The quadratic polynomial with integer coefficients is .
Step-by-step explanation:
Statement is incorrectly written. Correct form is described below:
<em>Find a quadratic polynomial with integer coefficients which has the following real zeros: </em><em>. </em>
Let be and
roots of the quadratic function. By Algebra we know that:
