An electrical company claims that an average life of bulbs it manufactures is 1200 hourswith a standard deviation of 250 hours. If a random sample of 100 bulbs is chosen, what isthe probability of the sample mean will be:a.Greater than 1150 hours?b. Less than 1250 hours?C. Between 1150 and 1250 hours?

Given that : μ= 1200 hour ? = 250 hours n = 100 By using the central limit theorem we solve this…
