Problem: Can someone please provide some assistance with this question. Its for an MBA course. There are two questions and each question needs to be between 350 and 400 words or more. Maximum number of characters 60,000. Explain the difference between the null hypothesis and alternative hypothesis. Which one can be proven in a statistical sense? How can you determine when to use a lower one-tailed test of hypothesis versus an upper one-tailed test? Thank you so much in advance for all your help.
