    You have 100 light bulbs whose lifetimes are modeled by an independent exponential distribution with a mean of 8 hours. The bulbs are used one at a time, with a failed bulb being replaced immediately with a new one. Use the central limit theorem to approximate the probability that there is still a working bulb between 790 hours and 820 hours

    You have 100 light bulbs whose lifetimes are modeled by a uniform distribution from 0 to 16 hours with a mean of 8 hours. The bulbs are used one at a time, with a failed bulb being replaced immediately with a new one. Use the central limit theorem to approximate the probability that there is still a working bulb after 850 hours.

    Page 1 Question 1 Suppose we take repeated random samples of size 20 from a population with a Select all that apply. mean of 60 and a standard deviation of 8. Which of the following statements is 10 points true about the sampling distribution of the sample mean (x)? Check all that apply. A. The distribution is normal regardless of the shape of the population distribution, because the sample size is large enough. B. The distribution will be normal as...
