Description:A researcher wanted to find the effect of a special diet on the systolic blood pressure of high blood patients. She selected a sample of 7 adultsin placed them on a dietary plan for 2 months.Use a 5% level of significance to test that there is a significant difference between before and after. The following data were recorded:Table 1. Systolic blood pressure of patients before and after the dietPatientAВCEFGВР210180190220230210220(BEFORE)ВР (AFTER)190150170180150160170
