What is the probability of the length of a randomly selected cane being between 360 and 370 centimetersThe mean is μ=365.45, and the standard deviation is σ=4.9. As the probability between two values is to be calculated, subtract the probability of the lower value from the higher value. In this case, you have to use the NORMDIST function twice.Suppose that the weight of navel oranges is normally distributed with a mean of μ=6 ounces and a standard deviation of σ=0.8 ounces. Find the weight below that one can find the lightest 90% of all navel orangesThe weights of bags of raisins are normally distributed with a mean of 175 grams and a standard deviation of 11 grams. Bags in the upper 4.5% are too heavy and must be repackaged. Also, bags in the lower 5% do not meet the minimum weight requirement and must be repackaged. What are the ranges of weights for raisin bags that need to be repackagedThe average speed of a car on the highway is 85 kmph with a standard deviation of 5 kmph. Assume the speed of the car, X, is normally distributed. Find the probability that the speed is less than 80 kmph.A normal distribution curve is a symmetric bell-shaped curve, continuous for all the values of X between −∞ and ∞. The parameter μ is the mean of the normal distribution, and σ is its standard deviation. The graph of a normal distribution is called the normal curve. A normal curve with mean μ and standard deviation σ is shown below. [Show More]
