In elderly patients with hypertension, a high systolic pressure can cause a fainting episode, soXtransporting them to an emergency clinic is imperative. Let be the systolic blood pressure of elderlypatients with hypertension on arrival at the emergency clinic after a fainting episode. A random sample ofsuch patients was considered. The measurements of each patient, in mm Hg, are given below. At the 5%level of significance, can we conclude from the data in this sample that the mean systolic blood pressure ofall elderly hypertensive patients transported to an emergency clinic after a fainting episode is smaller than175 mm Hg?patient123456789101112131415X166178153157178158153169182155151195202169157patient161718192021222324252627282930X173161155154178200168196180191167170161191166patient313233343536373839404142434445X167163157201204159154192162182165190154150194patient464748495051525354555657585960x1821961691581801991821781611701681581591691631
