The drinking water demand of a city follows a normal distribution with a mean of 700 m^3 per day and a standard deviation of 125 m^3. The water distribution network can provide a constant rate of supply of 900 m^3 per day. If the standard error of the estimated water distribution network capacity is 100 m^3, determine the risk of failure on a typical day.

With a mean of 16, a Poisson distribution can be approximated by a normal distribution with the same mean. It is known that, under a normal distribution, in between the two lines [mean - 1 standard deviation] and [mean + 1 standard deviation] approximately 68% of the area under the normal curve is covered. If Bigfield is facing its peak demand period with an average of 16 jobs per day and its capacity is set at 20 jobs per day,...

The demand for water in a certain town (in million gallons) follows an exponential distribution with (lambda)=1/8 If the capacity of the water resources is of 10 million gallons, what is the probability that in any given day, the supply will not be enough? In the next 10 days, what is the probability that we would have a water shortage in exactly two days? If an inspector arrives, and every day checks if there is a water shortage, how many...

Given that Kansas City men's height follows a normal distribution with its mean of 69 inches and standard deviation of 2.5 inches, are the following statements true or false? Omaha men's height is known to follow a normal distribution with its mean of 68.5 inches and standard deviation of 2.7 inches. A 71 inch tall man would place higher in percentile in Kansas City than in Omaha If the median is at 67.5 inches, the distribution is positively skewed

In order to provide drinking water as part of its 50-year plan, a west coast city is considering constructing a pipeline for importing water from a nearby community that has a plentiful supply of brackish ground water. A full-sized pipeline can be constructed at a cost of $125 million now. Alternatively, a smaller pipeline can be constructed now for $75 million and enlarged 18 years from now for another $110 million. The pumping cost will be $25,000 per year higher...

The amount of water consumed each day by a healthy adult follows a normal distribution with a mean of 1.44 liters. A health campaign promotes the consumption of at least 2.0 liters per day. A sample of 10 adults after the campaign shows the following consumption in liters: 1.80 1.94 1.70 1.50 1.64 1.40 1.64 1.70 1.66 1.54 At the 0.100 significance level, can we conclude that water consumption has increased? Calculate and interpret the p-value. State the null hypothesis...
