The amount of time a certain brand of light bulb lasts is normally distribued with a mean of 1500 hours and a standard deviation of 40 hours. Out of 545 freshly installed light bulbs in a new large building, how many would be expected to last between 1430 hours and 1540 hours, to the nearest whole number?

C. The random sample of 625 batteries taken by the consumer organisation turned out to have a mean operating time of 19.35 hours. Does this sample look like it belongs to the sampling distribution displayed in Figure 1? Explain/Justify your answer. [Does this sample likely to happen?] Type your answer in this space - the box will expand automatically d. Given that the sample was randomly selected from all batteries manufactured by the Betterbuy Battery Company in March, and given that each battery's operating time was measured accurately, what conclusion can we reach from part (c)?

The mean IQ of 200,000 current and past University of Manitoba students has been found to be 81.9. The standard deviation was found to be 13.1. The student enrollment at the University of Manitoba in 2016 was 29,987. The minimum IQ to be able to graduate from the University of Winnipeg has been found to be 104. Of the 29,987 students at the University of Manitoba in 2016, how many would be expected to be smart enough to graduate from the University of Winnipeg? Assume a Gaussian distribution.
