Answer:
Step-by-step explanation:
Left = 2000 * (1/2)^x
Try it.
x = 1
Left = 2000 * (1/2)^1
left = 2000 * 1/2
left = 1000
x = 3
left = 2000 (1/2)^3
left = 2000 (1/8)
left = 250
x = 4
left = 2000 * (1/16)
left = 125
from her on the function does not work accurately. You have to modify the algorithm.
Answer:
The critical values of F at 95% confidence are 0.359 and 2.788.
Step-by-step explanation:
We are given that a sample of 21 days of sales at Store A and a sample of 16 days of sales at Store B indicated the following:
Store A Store B
nA = 21 nB = 16
SA = 28.284 SB = 20
And we are interested in determining whether or not the variances of the sales at two small grocery stores are equal.
AS we know that when we are interested in variances of two samples, we use F-test for doing hypothesis testing.
The test statistics for F-test is = ~
where, and are sample standard deviations.
Now, the critical values of F at 2.5% (because two-tailed test) level of significance from F-table at degrees of freedom (21 - 1, 16 - 1) = (20, 15) are given as;
2.788 for right-part and 0.359 for the left-part.
Answer:
P > 9
Step-by-step explanation:
first, you add 3 to both sides,
2p > P + 9
then subtracts P from both sides,
P > 9
your final answer is P > 9
