b) A bottled water company has found in the past that 2% of their bottled water does not meet the company's high standards. As such periodic samples are taken and tested for their quality. If from the last batch a sample of 12 bottles are taken and tested, determine the probability: iv. Calculate the probability that at most 2 bottles do not meet the company's Standards V. The expected number of bottles that do not meet the company's standards. c) The amount of sodium sulfate, in mg, found in the bottled water follows a normal distribution with a mean 13mg and a standard deviation of 2.5mg. It is known that 76% of the bottles have a mean that is more than x mg. Find the value of x.
