b) Assume that in a certain district the mean systolic blood pressure of persons aged 20 to 40 is 130 mm Hg with a standard deviation of 10 mm Hg. A random sample of 64 persons aged 20 to 40 from village X of the same district has a mean systolic blood pressure of 132 mm Hg. Does the mean systolic blood pressure of the dwellers of the village (aged 20 to 40) differ from that of the inhabitants of the district (aged 20 to 40) in general, at the 5% level of significance?

(b) Assume that in a certain district the mean systolic blood pressure of persons aged 20 to 40
is 130 mm Hg with a standard deviation of 10 mm Hg. A random sample of 64 persons
aged 20 to 40 from village X of the same district has a mean systolic blood pressure of 132
mm Hg. Does the mean systolic blood pressure of the dwellers of the village (aged 20 to
40) differ from that of the inhabitants of the district (aged 20 to 40) in general, at the 5%
