Help please! Confused
Mike thinks that there is a difference in quality of life
between rural and urban living. He collects information from
obituaries in newspapers from urban and rural towns in Idaho to see
if there is a difference in life expectancy. A sample of 5 people
from rural towns give a life expectancy of xr¯=76.6 years with a
standard deviation of sr=8.74 years. A sample of 4 people from
larger towns give xu¯=81.9 years and su=7.91 years. Does this
provide evidence that people living in rural Idaho communities have
different life expectancy than those in more urban communities? Use
a 10% level of significance. (a) State the null and alternative
hypotheses: (Type ‘‘mu_r′′ for the symbol μr , e.g. mu_rnot=mu_u
for the means are not equal, mu_r>mu_u for the
rural mean is larger, mu_r<mu_u , for the rural
mean is smaller. )
H0 =
Ha =
(b) The degree of freedom is
(c) The test statistic is
(d) Based on this data, Mike concludes:
A. There is not sufficient evidence to show that
life expectancies are different for rural and urban
communities.
B. The results are significant. The data seems to
indicate that people living in rural communities have a different
life expectancy than those in urban communities.
