Question 820296
10. Answer True or False to each of the following
a) The margin of error is always greater than or equal to the standard error.
ME = z*s
Since -oo < z < oo, the answer is false.
-----------------------------------------
b) If a test is run and p=0.0356, then we can reject Ho at alpha = 0.01.
Ans: true
--------------------
c) If a 95% CI for the difference in two independent means is (-4.5 to 2.1), then the point estimate is -2.1.
----
Find the midpoint of the endpoints::
2*point estimate = -4.5+2.1 = -2.4
point estimate = -1.2
Ans: false
---------------------------------------------
d) If a 95% CI for the difference in two independent means is (2.1 to 4.5), there is no significant difference in means
Ans: False because 0 is not in the interval.
