Credit Card Balances To test the claim that the mean credit card debt for individuals is greater
Question:
Credit Card Balances To test the claim that the mean credit card debt for individuals is greater than $5000, you do some research and find that a random sample of 6 cardholders has a mean credit card balance of $5434 with a standard deviation of $625. You conduct a statistical experiment where Ho $5000 and H > $5000. At a = 0.05, explain why you cannot reject Ho. Assume the population is normally distributed. (Adapted from TransUnion)

I have recently received the degree of PhD. In Physics by the Universidade Federal do Maranhão after spending a term in Durham University, as I have been awarded a scholarship from a Brazilian mobility program. During my PhD. I have performed research mainly in Theoretical Physics and published works in distinguished Journals (check my ORCID: https://orcid.org/0000-0002-4324-1184).
During my BSc. I have been awarded a scholarship to study for a year in the University of Evansville, where I have worked in detection-analysis of photon correlations in the the Photonics Laboratory. There I was a tutor in Electromagnetism, Classical Mechanics and Calculus for most of that year (2012).
I am very dedicated, honest and a fast learner, but most of all, I value a job well done.
