Chapter 5: Normal Probability Distributions38. [APPLET] Milk Consumption You are performing a study about weekly per capita milkconsumption. A previous study found weekly per capita milk consumption to be normallydistributed, with a mean of 48.7 fluid ounces and a standard deviation of 8.6 fluidounces.

Question Help An elevator has a placard stating that the maximum capacity is 1650 lb-10 passengers. So, 10 adult male passengers can have a mean weight of up to 1650/10= 165 pounds. If the elevator is loaded with 10 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 165 lb. (Assume that weights of males are normally distributed with a mean of 167 lb and a standard deviation of 28 lb.) Does this elevator appear to be safe? The probability the elevator is overloaded is 0.5894. (Round to four decimal places as needed.) Does this elevator appear to be safe?

Number of accidents for American drivers follows a normal distribution. Four Americans who are no longer driving were randomly selected. What is the probability that their average number of accidents while driving will be larger than 4? P(E > 125) For this problem, we were told that the distribution is normal. If the shape of the distribution was not stated, we would not have been able to use the normal distribution table to find the probability, What does the Central Limit Theorenm tell us to do to be able to normalize the distribution?

Resources Giye Up? The number of flaws per square yard in a type of carpet material varies with mean 1.6 flaws per square yard and standard deviation 1.2 flaws per square yard. Without doing any calculations, explain why you cannot use a Normal distribution to calculate the probability of randomly selecting a 1 square yard of material and finding 2 or more flaws. O You cannot use a Normal distribution to calculate the probability of randomly selecting a 1 square yard of material and finding 2 or more flaws because it is impossible for carpet to have 1.6 flaws. You cannot use a Normal distribution to calculate the probability of randomly selecting a1 square yard of material and finding 2 or more flaws because the population distribution is not Normal and the sample size is not at least 30. You cannot use a Normal distribution because the Normal distribution only applies to proportions. You cannot use a Normal distribution to calculate the probability of randomly selecting a 1 square…
