    Statistics is hard




    Hi

    I am having trouble with these two questions, wondering if anyone can help. Thank you in advance. I have attached the data set.

    (a) Test, at the 5% level of significance, whether the average profit in 2014 differs between businesses located in Parramatta CBD or located in Sydney CBD.

    [You may assume that the unknown population standard deviations for Parramatta and Sydney businesses are equal]

    (b) Test, at the 5% level of significance, whether location (Parramatta or Sydney CBD) of the business is related to type of business (privately held, publicly traded or franchise)?


    Thank you

    I can't open you results on my system, are you asking what type of test or if your results are right?
    Both of these questions can be addressed with t test.
