Amanufacturer 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 volts, 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.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

step-by-step explanation:

if you was gonna solve for a, a is a   < -12
