A manufacturer is interested in the output voltage of a power supply used in a PC. Output voltage is assumed to be normally distributed with standard deviation 0.25 volt, and the manufacturer wishes to test
H0:μ=5
volts against
H1:μ≠5
, using n = 8 units. a. The acceptance region is 4.85 ≤
x¯¯¯≤5.15
. Find the value of α. b. Find the power of the test for detecting a true mean output voltage of 5.1 volts.

a= 0.0897

b= 0.71186

Power of the test for detecting a true mean output voltage of 5.1 volts is 0.28814.

Step-by-step explanation:

See attached pictures.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
