Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Let Z represent the reading of this thermometer at freezing. What reading separates the highest 5.6% from the rest? That is, if P(z> c) = 0.056, find c. C= °℃

On an exam with µ = 52, a person has a score of X = 44. Which value for the standard deviation would give this person the highest position in the class distribution? Group of answer choices σ = 2 σ = 4 σ = 8 This is impossible to determine based on the information provided..

For samples of the specified size from the population described, find the mean and standard deviation of the sample meanx. The National Weather Service keeps records of snowfall in mountain ranges. Records indicate that in a certain range, the annual snowfall has a mean of 83 inches and a standard deviation of 14 inches. Suppose the snowfalls are sampled during randomly picked years. For samples of size 49, determine the mean and standard deviation of x A) μ=83; 0x=2 B) μ = 2; σ= 83 Oc C) μ = 83; σ= 14 D) u 14; = 83 =

A normal population has mean  =μ9  and standard deviation  =σ5 . Find the proportion of the population that is greater than  4 . Round the answers to at least four decimal places.     The proportion of the population that is greater than  4  is    .
