Suppose we computed two trapezoidal rule approximations to the
integral. An initial course estimate with segment length 0.61
approximated the integral as 16.1. A second finer estimate with a
segment width half that of our first estimate was found to be 18.1.
Using these two approximations, find an approximation with error
O(h4).
Input your solution to three decimal places.
Using the Composite Trapezoidal Rule, with evenly spaced nodes,
and n=3, find an approximate value for interval where b=1 and a=0,
e^(-x^2)dx. Estimate the error.
1) If we are given a confidence interval, how do we know the margin of error that was used to calculate the confidence interval? You may explain and then provide an example.
2) What is the best way to make a confidence interval more precise, while preserving accuracy? How do we see this in the formula for margin of error?
While using crunchit/ excel/ software of your choose how do you
find a confidence interval when your variables are in words? i have
a list of over 300 patients who are positive or negative for
influenza and I'm not sure how to solve!
Descartes' Rule of signs Use Descartes' Rule positive and how of
Signs to determine how many negative real zeros of the polynomial
can have. Then determine the possible total number of real
zeros.
P(x) = x^3 - x^2 - x - 3
P(x) = 2x^3 - x^2 + 4x -7
P(x) = 2x^6 + 5x^4 - x^3 -5x -1
P(x) = x^4 + x^3 + x^2 + x + 12
P(x) = x^5 + 4x^3 - x^2 + 6x
P(x)...
A. How many samples do you need to create a 99% confidence
interval for u with a margin of error fo 10 and standard deviation
of 28?
B. Five a 95% percent confidence interval for the true mean if
the sample mean is 86.5, the sample size is 70, and the standard
deviation is 12.2.
