3. The output voltage for an electric circuit is specified to be
130. A sample of 40 independent readings on the voltage for this
circuit gave a sample mean 128.6 and standard deviation 2.1. Test
the hypothesis that the average output voltage is 130 against the
alternative that it is less than 130. Use a test with level
.05.
could you please amnswer in r coding i am using jupyter
