Answer:
A
Step-by-step explanation:
If you simplify you get -45=75 and that’s not true.
At the end of the directions, it talks about parallel, perpendicular, or neither. When x=y, the lines are perpendicular and have infinite solutions. When they are parallel, there is no solution. You'll get an answer like 4=5. Neither means there is only one answer, and you will get one x and one y.
Answer:
Correct option is (C).
The possible value of the <em>p</em>-value for a one-tailed test are 0.22 and 0.78.
Step-by-step explanation:
The <em>p</em>-value is the probability of acquiring a result as extreme as the observed result, assuming the null hypothesis statement is true.
The <em>p</em> value of a test is:
Left-tailed test:
Right-tailed test:
.
Here,
TS = Test statistic
ts = computed value of the test statistic.
The two-tailed <em>p</em>-value is:
or
.
The <em>p</em>-value of the two tailed test is, 0.44.
Compute the <em>p</em>-value for one-tailed test a follows:


Thus, the possible value of the <em>p</em>-value for a one-tailed test are 0.22 and 0.78.
The correct option is (C).
