Assume that the readings at freezing on a batch of thermometers are Normally distributed with mean 0∘C and standard deviation 1.00∘C. Find P90, the 90 -percentile of the distribution of temperature readings. This is the temperature reading separating the bottom 90% from the top 10%. ∘C Round to 2 places.
The mean daily production of a herd of cows is assumed to be normally distributed with a mean of 32 liters, and tandard deviation of 8.3 liters. A) What is the probability that daily production is between 23.5 and 28.6 liters? Do not round until you get your your inal answer. Answer= (Round your answer to 4 decimal places.) Warning: Do not use the Z Normal Tables.. they may not be accurate enough since WAMAP may look for more accuracy than comes from the table.
The daily milk production of a herd of cows is assumed to be Normally distributed with a mean of 31 liters, and standard deviation of 6.8 liters. A) On what proportion of days is daily production less than 39 liters? Answer = (Round your answer to 3 decimal places.) B) On what proportion of days is production more than 32.4 liters? Answer = (Round your answer to 3 decimal places.)
