I need to code this into MATLAB and have no idea why it is not working.

A health care company performed a study to validate a translated version of the Western Ontario and McMaster University index (WOMAC) questionnaire used with spanishspeaking patients with hip or knee osteoarthritis. For the 76 women classified with severe hip pain. The WOMAC mean function score was 70.7 with standard deviation of 14.6. We wish to know if we may conclude that the mean function score for a population of similar women subjects with sever hip pain is less than 75 . Let α =0.01. [Hint: population is large enough to be considered to have a Gaussian distribution, set H0: Mean WOMAC = 75, data given includes: n=76, μX = 70.7, σ = 14.6, α =0.01 ].

This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the free MATLAB Onramp tutorial ( https://www.mathworks.com/support/learn-with-matlab-tutorials.html ) to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.
