A company that makes LED light bulbs claims that the bulbs have a lifetime of 11,000 hours. Quality control tests a random sample of 45 light bulbs to determine if the lifetime is less than 11,000 hours at a confidence level of 0.05.

From the histogram, can normality be assumed? YES or No

Since the p-value is____ (GREATER or LESS) than the significance level0.05, the null hypothesis ____ (FAIL TO BE REJECTED or REJECTED)(SUFFICIENT OR INSUFFICIENT) ______evidence exists that the mean lifetime is less than 11,000 hours.
