Hypothesis Testing explanation
Hypothesis Testing presents a sample of the number of defective flash drives produced by a small manufacturing company over the last 30 weeks. The company’s operations manager believes that the number of defects produced by the process is less than seven defective flash drives per week.
Your hypothesis test should include null and alternative hypotheses, a t test statistic value, a p-value, a decision, and a conclusion.
