A clinical trial was conducted to determine if women who have regular mammograms to screen for breast cancer would decrease breast cancer mortality. The null hypothesis is women who have regular mammograms have the same breast cancer mortality rate as women who do not have regular mammograms. The alternative hypothesis is women who have regular mammograms have a lower breast cancer mortality rate than women who do not have regular mammograms. A hypothesis test was conducted and the results were not statistically significant. Does that mean that the null hypothesis is true, that women who have regular mammograms have the same breast cancer mortality rate as women who do not have regular mammograms
