Small-business telephone users were surveyed 6 months afteraccess to carriers other than Carrier A became available for​wide-area telephone service. Of a random sample of
260260
Carrier A​ users,
158158
said they were attempting to learn more about their​ options, asdid
206206
of an independent random sample of
240240
users of alternate carriers.​ Test, at the
11​%
significance level against a​ two-sided alternative, the nullhypothesis that the two population proportions are the same.
Let
Upper P Subscript xPx
be the proportion of Carrier A users who said they wereattempting to learn more about their options and
Upper P Subscript yPy
be the proportion of users of alternate carriers who said theywere attempting to learn more about their options.
H1=?
H0=?
The test statistic is Z=?
The critical​ value(s) is(are)=?
Since the test statistic is NOT MORE EXTREME/MORE EXTREME=?
than the critical​ value(s) DO NOT REJECT/REJECT=?
Upper H 0H0.
There is SUFFÄ°CÄ°ENT/UNSUFFÄ°CÄ°ENT=?evidence to conclude thatthere is a difference between the two population proportions.
