BIG Corporation advertises that its light bulbs have a mean lifetime,

, of at least

3000

hours. Suppose that we have reason to doubt this claim and decide to do a statistical test of the claim. We choose a random sample of light bulbs manufactured by BIG and find that the mean lifetime for this sample is

2860

hours and that the sample standard deviation of the lifetimes is

600

hours.

Based on this information, answer the questions below.

What are the null hypothesis (H0) and the alternative hypothesis (H1) that should be used for the test?

H0: μ is ?

less than

less than or equal to

greater than

greater than or equal to

not equal to

equal to

H1: μ is ?

less than

less than or equal to

greater than

greater than or equal to

not equal to

equal to

In the context of this test, what is a Type II error?

A Type II error is

rejecting

failing to reject

the hypothesis that μ is ?

less than

less than or equal to

greater than

greater than or equal to

not equal to

equal to

when, in fact, μ is

less than

less than or equal to

greater than

greater than or equal to

not equal to

equal to

Suppose that we decide to reject the null hypothesis. What sort of error might we be making?

Type I

Type II
