First you find the zeros/x-intercepts using the factors already given in the inequality.
Therefore we make our solution using the interval notation.
Answer:
So the value of the test statistic is -0.85.
Step-by-step explanation:
We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.
We get that:
We calculate the standar deviation:
We calculate the value of the test statistic:
So the value of the test statistic is -0.85.
