Question: A manufacturer claims that the average life time of an electronic component is at least 40 hours. A sample of 50 components average life time was calculated, and the decision was to reject the null hypothesis from the test statistic. Which of the following statements states the conclusion? Steps to derive 1 H0 : μ ≥ 40 and H1 : μ < 402 The decision from the test statistic was rejected the null hypothesis.3 So, the manufacturer's claim is wrong, the average life time of the electronic component is less than 40 hours.Hence the right answer is Option D Click Here To Go Back If the functions are defined by f(x) = x + 5 and g(x) = | x + 3 |, then what is..
