1pts A staff member at UFs Welliness Center is interested in seeing if a new stress reduction progam will lower employees ypstolic blood pressure levels. Twenty people are selected and have their blood pressure measured. Each pervon then participates in the stress reduction program. One month after the stress reduction program, the systolic blood pressurelevels of the employees were systolic blood pressure" minus "After blood pressure" The

confidence interval was (

). The population mean systolic blood pressure levels after the stress reduction program were sigificanty higher than the population mawn vpatic blood pressure levels before the stress reduction program, at the

confidence level. We are

confident that there is no difference in population average systolic blood pressure levels before and atter the stress reduction proyan. The population mean blood pressure levels before the stress reduction program were significanty higher than the popiation mean syatolic Dlood pressure levels after the stress reduction program, at the

confidence level.
