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 V, and the manufacturer wishes to test H0: μ = 9 V against H1: μ ≠ 9 V with a sample of n = 10 units.
(a) The critical region is defined as , find the type I error probability α.
(b) Find the power of the test for detecting a true mean output voltage of 9.1 V.
c) Find the type I error probability α and the power of the test when n = 16 batches and the boundaries of the critical region do not change.
(d) Suppose that the process engineer wants the type I error probability for the test to be α = 0.05. Where should the critical region be located?

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. The manufacturer
wishes to test H0: μ=5 volts against H1: μ≠5
volts using α=0.10. Suppose a sample size of 8 power supply units
is used and you are interested in computing the probability the
test will fail to detect a true mean output voltage of 5.1 volts.

Problem 4. A high-voltage power supply should have a nominal
output voltage of 350 V. A sample of four units is selected each
day and tested for process-control purposes. The data (see sheet
Problem4 in Homework 4.xlsx) give the difference between the
observed reading on each unit and the nominal voltage times ten;
that is, ?? = (observed voltage on unit ? - 350)*10 (a) Set up ?̅

A high-level voltage power supply should have a nominal output
voltage of 350 V. A sample of four units is selected each day and
tested for process-control purposes. The data (20 days, 1
sample/day) shown in the table below give the difference between
the observed reading on each unit and the nominal voltage times
ten; that is, xi = (observed voltage on unit
350)*10.

A
power supply produces voltage described as V= 100sin(60t). what is
the average value of this voltage and what is the average voltage
squared?
The average voltage is supposed to be 0V and then the avg
voltage squared is supposed to be 5000 V^2 which makes zero sense
to me. Thanks!
