Answer: The point estimate of the population is 0.415 round to the nearest thousandth as needed.the margin error is 0.189 .
Step-by-step explanation:
Let be the sample mean .
We know that the confidence interval for population mean is given by :-
, where E is the margin of error .
Given : Lower bound of the confidence interval = 0.226
Upper bound of the confidence interval =0.604
i.e.
Adding (1) from (2), we get
From (2),
Hence, the point estimate of the population is 0.415 round to the nearest thousandth as needed.the margin error is 0.189 .
Answer:
temp after 7 minutes is 135°
temp after 't' minutes: y = 65 + 10t
Step-by-step explanation:
Answer: width is 12, length is 16
Step-by-step explanation:
A= l*w
l=w+4
A=w(w+4)
factor
(w+16)(w-12)
w= -16 or w=12
width is 12, length is 16
-83/40
There is no way this is college math lol
I) The probability that it is not bruised is 1-0.054=0.946
Hint for ii and iii) use Bayes Theorem
