Answer:
0.37072
Step-by-step explanation:
Let A be the event that step 1 is defective (P(A) = 10%), B the event that step 2 is defective(P(B) = 20%), C the event that step 3 is defective (P(C) = 8%), D the event that step 4 is defective(P(D) = 5%). Let us suppose that the occurance of a failure at any step is indepent of the other steps.
Recall the following properties
And given A, B, C, D independent , then
REcall that if the a set of events A,B,C,D are independent, their complements are also indepent.
Since we are asked for the probability of a defective item, this means that at least one of the steps is defective. Then, we are asked for the following probability:
Answer:
B). F(1, 12) = 16.00
Step-by-step explanation:
'ANOVA' is a measure employed for 'analysis of a variance' in a given set of data of treatments or populations. While t-test helps in comparing their means.
As per the question, the F-ratio using ANOVA would be 'F(1, 12) = 16.00.' In order to calculate the variances, the distinction among the samples. The б^2 denotes the difference of representative means which is augmented by n(in case of samples being same). So, the ratio of F(1, 12) would be б^2 i.e. 4^2 = 16 since the sample sizes are distinct. Thus, <u>option B</u> is the correct answer.
Answer:
v^2 over 4u^2
Step-by-step explanation:
Answer:
x=48
Step-by-step explanation:
Since these angles are supplementary, they add up to 180. so, you can set the equation x+23+x+61=81. Simplify the equation and solve for x
