Marketers believe that 65.94% of adults in the U.S. own a cell phone. A cell phone manufacturer believes the proportion is different than 0.6594. 49 adults living in the U.S. are surveyed, of which, 37 report that they have a cell phone. Using a 0.10 level of significance test the claim. The correct hypotheses would be: О Но:р< 0.6594 HA:p > 0.6594 (claim) ОНо:р> 0.6594 HA:p < 0.6594 (claim) О Н:р — 0.6594 HA:p + 0.6594 (claim) Since the level of significance is 0.10 the critical value is 1.645 and -1.645 The test statistic is: (round to 3 places) The p-value is: (round to 3 places) The decision can be made to: O reject Ho O do not reject Ho The final conclusion is that: O There is enough evidence to reject the claim that the proportion is different than 0.6594.

Question
Marketers believe that 65.94% of adults in the U.S. own a cell phone. A cell phone manufacturer believes
the proportion is different than 0.6594. 49 adults living in the U.S. are surveyed, of which, 37 report that
they have a cell phone. Using a 0.10 level of significance test the claim.
The correct hypotheses would be:
О Но:р< 0.6594
HA:p > 0.6594 (claim)
O Ho:p > 0.6594
HA:p < 0.6594 (claim)
О Но:р — 0.6594
HA:P + 0.6594 (claim)
Since the level of significance is 0.10 the critical value is 1.645 and -1.645
The test statistic is:
(round to 3 places)
The p-value is:
(round to 3 places)
The decision can be made to:
O reject Ho
O do not reject Ho
The final conclusion is that:
O There is enough evidence to reject the claim that the proportion is different than 0.6594.
O There is not enough evidence to reject the claim that the proportion is different than 0.6594.
O There is enough evidence to support the claim that the proportion is different than 0.6594.
O There is not enough evidence to support the claim that the proportion is different than 0.6594.
