WebA set of 40 high-efficiency pumps is tested. All of the pumps fail ( \( F=40) \) after 400 pump hours of operation ( \( T=400 \) ). It is believed that the time to failure of the pumps follows an exponential distribution. Using the following table and the Chi-Square Goodness-of-Fit method, determine if the exponential distribution is a good choice. WebJun 10, 2024 · The p-value for the Chi-Square test is 2.53, and the Chi-Square test statistic is 60.36. Remember that the null and alternative hypotheses for a Chi-Square Goodness of Fit Test are as follows: H 0: The distribution of a variable is based on a hypothesis. H 1: A variable differs from the expected distribution. phenomene paranormal a beauport
