The National Center for Health Statistics reports that the mean systolic blood pressure for males 50 to 59 years of age is 130. A researcher suspects that the mean should be larger than the one stated in the report. In conducting a hypothesis test, a sample of 80 males in that age group was obtained and the sample mean was 145. This result from the data would provide strong evidence against the mean stated in the report if we can show that __________________.

A. 130 could easily occur by pure chance alone (if we assume that the mean stated in the report is true)

B. 130 could not easily occur by pure chance alone (if we assume that the mean stated in the report is true)

C. 145 could easily occur by pure chance alone (if we assume that the mean stated in the report is true)

D. 145 could not easily occur by pure chance alone (if we assume that the mean stated in the report is true)
