Answer:
They are not parallel because their slopes are not equal
Step-by-step explanation:
Answer:
r = 2
Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)
(-1, -5)
(r, -9)
-5 - (-9) / -1 - r = 2
4 / -1 - r = 2
r = -2
-1 - (-3) = 2
4 / 2 = 2
Please let me know if I've gotten anything wrong!
Answer:
I would reject the null hypothesis.
Step-by-step explanation:
The test is a two-tailed test because it is stated that the alternate hypothesis is two-sided.
Degree of freedom = n - 1 = 350 - 1 = 349
At 349 degrees of freedom and 5% significance level, the critical values are -1.96702 and 1.96702
Conclusion:
Reject the null hypothesis because the test statistic 3 falls outside the region bounded by the critical values -1.96702 and 1.96702.
