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 volts against volts, using units. In your intermediate calculations, use z-scores rounded to two decimal places (e. g. 98.76). Round your answers to four decimal places (e. g. 98.7654). (a) The acceptance region is . Find the value of . (b) Find the power of the test for detecting a true mean output voltage of 5.1 volts.

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

the answer is d

hope this
