I need helping knowing which continuity correction factor to use (whether +.5 or -.5,…) when we have Binomial Distributions.
ANSWER:
Continuity Correction Factor – adding or subtracting .5:
use the following table to decide whether to add or subtract.
If P(X = n) use P(n – 0.5 < X < n + 0.5)
If P(X > n) use P(X > n + 0.5)
If P(X ≤ n) use P(X < n + 0.5)
If P(X < n) use P(X < n – 0.5)
If P(X ≥ n) use P(X > n – 0.5)
Which correction factor should we use?
A blog reported that 6% of cab drivers read texts while driving. If 200 drivers are randomly selected, find the probability that
(a) 10 or more read texts while driving.
(b) 35 to 39 read texts while driving.
(c) exactly 40 read texts while driving.
(d) At least 35 read texts while driving.
(e) 2 or fewer read texts while driving.
(f ) at most 26 read texts while driving.
(g ) exactly 15 read texts while driving.
I think I covered all possibilities you will see in this course with the examples above!
