Choose the appropriate hypotheses and identify the test as one-sided or two-sided.
H 0: p=.35
H a: p >.35
The test is one-sided.
H 0: p=.35
H a: p ?.35
The test is one-sided.
H 0: p=.35
H a: p ?.35
The test is two-sided.
H 0: p=.35
H a: p<.35
The test is two-sided.
H 0: p=.35
H a: p<.35
The test is one-sided.
H 0: p=.35
H a: p>.35
The test is two-sided.
| A. | H 0: p=.35 H a: p >.35 The test is one-sided. | |
| B. | H 0: p=.35 H a: p ?.35 The test is one-sided. | |
| C. | H 0: p=.35 H a: p ?.35 The test is two-sided. | |
| D. | H 0: p=.35 H a: p<.35 The test is two-sided. | |
| E. | H 0: p=.35 H a: p<.35 The test is one-sided. | |
| F. | H 0: p=.35 H a: p>.35 The test is two-sided. |
Solution
H 0: p=.35
H a: p >.35
