A recent study of 1,337,000 people showed that people think about Economics an
average of 5 times per minute (E). If sd (Ebar) =2, and some Sociologists claim that
it is unhealthy to think about Economics more than 2 times per minute, what is
the conclusion from testing the following hypothesis (\alpha =0.05) :
H_(0):\mu _(E)<=2
H_(a):\mu _(E)>2
Select one:
a. Since H_(0)t>t^(*)H_(0)95%t>t^(*)H_(0)95%H_(0)t, do not reject H_(0) at a
95% confidence level. People think
about Economics less than twice a
minute, on average.t, do not reject H_(0) at a
95% level of significance. People
think about Economics less than
twice a minute, on average.
b. Impossible to determine.
c. Since t>t^(*), reject H_(0) at a 95%
confidence level. People think
about Economics more than twice
a minute, on average.
d. Since t>t^(*), reject H_(0) at a 95% level
of significance. People think about
Economics more than twice a
minute, on average.
e. Since t, do not reject H_(0) at a
95% confidence level. People think
about Economics less than twice a
minute, on average.
