The incubation period for the eggs of a House Wren has a normal probability distribution with a mean time of 336 hours and a sta
ndard deviation of 3.5 hours. Before hatching, a particular House Wren egg incubated for 343 hours. What is the probability that House Wren eggs will take longer than 343 hours to hatch? 68% 95% 32% 16% 5% 2.5%
1 answer:
Answer:
2.28%
Step-by-step explanation:
If X is the random variable that measures the time of incubation needed before hatching, we want
P(X>343)
This is the area under the normal curve whose mean is 336 hours and its standard deviation 3.5 hours to the right of the point 343. (See picture attached)
This can be done easily with the help of a computer and we find
P(X>343) = 0.0228 or 2.28%

"Raw" most nearly mean as used in line 74 is unfiltered.
Given a passage that is shown in the attached images.
Option A is the best answer. From lines 73 to line 75, the passage speaks to the modern belief that "the job of journalists should be to 'make news as it is, without putting their prejudices on it'". In this context, "raw" means unfiltered or in its most basic state.
