A new type of light bulb may have a mean lifetime of 15
(thousand hours), the current mean being 10.8035. This claim could
be verified by testing H0:
= 10.8035, vs. H1:
10.8035. If one were to make use of the critical region being
specified by 
14,
and
1 = 16.01.
What is the value of 
?

An electrical firm manufactures a certain type of LED light bulb and claims that the average bulb lifetime is at least 800 hours
An electrical firm manufactures a certain type of LED light bulb and claims that the average bulb lifetime is at least 800 hours. To test this, a random sample of 60 bulbs is taken. The average life of the sample is found to be 788 hours with a standard deviation of 40 hours.(a) At a level of 0.05 significance, is there compelling evidence to doubt the comp any's claim? Be sure to state the appropriate hypotheses, and specify the rejection...

A manufacturer of light bulbs advertises that, on average, its long-life bulb will last more than 5500hours. To test this claim, a statistician took a random sample of 90 bulbs and measured the amount of time until each bulb burned out. The mean lifetime of the sample of bulbs is 5551 hours and has a standard deviation of 420 hours. Can we conclude with 99% confidence that the claim is true? Fill in the requested information below. (a) The value...
