Suppose that a brand of lightbulb lasts on average 2069 hours with a standard deviation of 236 hours. Assume the life of the lightbulb is normally distributed. Calculate the probability that a particular bulb will last from 1592 to 2515 hours? P(1592 < X < 2515) = *4 decimal places. *Note: all z-scores must be rounded to the nearest hundredth.

In a recent year, grade 6 Ohio State public school students taking a mathematics assessment test had a mean score of 303.1 with a standard deviation of 36. Possible test scores could range from 0 to 1000. Assume that the scores were normally distributed. This is not a normal approximation, so do not correct for continuity. Find the probability that a student had a score higher than 295. Find the probability that a student had a score between 230 and 305. What is the highest score that would still place a student in the bottom 16% of the scores? If 4000 students are randomly selected, how many will have a test score that is less than 300? A random sample of 40 students is drawn from this population. What is the probability that the mean test score is greater than 290?
