Answer: The correct option is (D) 5.
Step-by-step explanation: We are given to select the correct value that would complete the following ordered pair if the point is on the graph f(x) = -2x + 3 :
(-1, ? ).
To find the required value, we must substitute x = -1 in the equation of the given function and find the value of f(x).
Therefore, at x = -1, we get
Thus, the required value is 5.
Option (D) is CORRECT.

Answer:
Explained below.
Step-by-step explanation:
(1)
The confidence level is, 91%.
Compute the value of α as follows:
(2)
As the population standard deviation is provided, i.e. <em>σ</em> = 256 psi, the <em>z</em> value would be appropriate.
The <em>z</em> value for α = 0.09 is,
<em>z</em> = 1.69
(3)
Compute the 91% confidence interval as follows:
(4)
The 91% confidence interval for population mean implies that there is a 0.91 probability that the true value of the mean is included in the interval, (2942.29, 3057.71) psi.
