Hey There!:
Sample Mean = 4.4823
SD = 0.1859
Sample Size (n) = 7
Standard Error (SE) = SD/root(n) = 0.0703
alpha (a) = 1-0.99 = 0.01
t(a/2, n-1 ) = 3.7074
Margin of Error (ME) = t(a/2,n-1)x SE = 0.2606
99% confidence interval is given by:
Sample Mean +/- (Margin of Error)
4.4823 +/- 0.2606 = (4.222 , 4.743)
Hope this helps!
The answer would be they have developed a strategy
Answer:
b
Explanation:
because it is the best one for that
Answer:
Probability (at least one bottle neck occurs during 8 hours of operation)
= 0.9817
Explanation:
Given:
Average bottleneck 1 hour = 0.5
Find:
Probability (at least one bottle neck occurs during 8 hours of operation)
Computation:
Expected events in 8 hour = 8(0.5)
Expected events in 8 hour = 4
Probability (at least one bottle neck occurs during 8 hours of operation) = p(X≥1)
Probability (at least one bottle neck occurs during 8 hours of operation) = 1-p(X=0)
Probability (at least one bottle neck occurs during 8 hours of operation) =1-exp(-4)[4⁰]/0!
Probability (at least one bottle neck occurs during 8 hours of operation) =1-0.0183
Probability (at least one bottle neck occurs during 8 hours of operation)
= 0.9817
30
Explanation:
with insurance from the emploryer the shot should atleast cost 30 of hand and the rest would be paid of 70 %
