The null, Ho, indicates that there is either no relationship or
a positive relationship between Amazon’s growth over the past ten
years and number of Best Buy brick and mortar
locations. The alternative, H1, seeks to prove that
there is a negative relationship between the variables, Amazon and
Best Buy brick and mortar locations. In other words, Amazon’s
growth is negatively impacting Best Buy by forcing store location
closures. Using a 95% confidence interval, construct a test of
hypothesis using the...
