Critical regions get larger as α values get smaller. T or F, and why or why not?
1 answer:
Answer: F
Critical regions get smaller as α-values get smaller.
Explanation:
The figure below shows the critical regions (shaded) for a 2-tailed test at the 95% confidence level.
Because the total area under the curve is 1, the α-value is 1 - 0.95 = 0.05.
It is split up into 0.025 for a two-tailed test. It remains at 0.05 for a one-tailed test.
The critical z-score at 95% confidence level is z* = 1.96.
When the α-value decreases:
(a) the z* value increases,
(b) the confidence level increases,
(c) the critical region decreases.
Critical regions get smaller as α-values get smaller.

Step-by-step explanation:
Since we want to get ' p ' on left hand side , remove the number ' - 6 '.
⇢ { The opposite of -6 is +6 and whatever we do to one side , we must do to the another side. So, I added 6 on both sides }
⇢ { On the left hand side , 6-6 = 0. That's how we removed the 6 so just 'p' is left. On the right hand side , 5+6 = 11 }
