Question 2 of 24 2 Points A certain electric circuit's output voltage is stated as 130. The sample mean of 40 separate voltage readings for this circuit was 128.6, with a standard deviation of 2.1. Compare the hypothesis that the average output voltage is 130 to the alternative hypothesis that it is less than 130. Use a 5% level of significance. Select the correct response: O Fail to reject null hypothesis O Reject null hypothesis O Need more data
