Question

Please show all work and explain. To test that the mean lifetime of light bulbs is no less than 900 hours (population is normally distributed and population standard deviation is 50), a random sample of 100 bulbs is tested, yielding a sample mean of 890 hours. What conclusion would you reach if alpha = .06? Show all the steps of hypothesis testing. You must state your conclusion in terms of the context of the mean lifetime of light bulbs.

Step 1

The null hypothesis (H₀) is that the mean lifetime of light bulbs is no less than 900 hours. The alternative hypothesis (H₁) is that the mean lifetime of light bulbs is less than 900 hours. H₀: μ ≥ 900 H₁: μ < 900 Show more…
