Page Loading Speed. widgetwarehouse. com is a popular e-commerce site that processes thousands of transactions every day. Tom, product manager at the site is analyzing some historical user data that widgetwarehouse. com has collected over several months to gain insights into how fast the site loads for each of its users. Tom knows that the time it takes each user to load the site follows a normal distribution with mean u= 351 milliseconds and standard deviation o= 7 milliseconds. Tom doesn't have a table or calculator with statistical capabilities, but he does know about the Normal distribution Tom wants to know more about the typical user's experience rather than any individual. He investigates the sample mean for samples of size n= 160,000, which is a typical number of visitors the site has each minute. Tom knows that the sampling distribution of the sample means also follows a normal distribution Because the sampling distribution is normal, you can use the empirical rule (68-95-99.7 rule) to calculate approximate probabilities for sample means as well. Use this fact to find the time that is greater than 99.85% of average loading times for samples of 160,000 users. (Report your answer in milliseconds rounding to 2 decimal places.)
