Answer:
a) Check graph
b)Closer to 0.5
c)Researcher 1 is right.
Step-by-step explanation:
a) Please check attached graph.
b) Please check second graph. It is shown that the value is 0.387 which is closer to 0.5.
c) Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. The researcher 1 is right because there are numerous random variables are exist for this event and normal distribution function is the best function that gives less error for this numerous not-known random variables.
We're told that
where the last fact is due to the law of total probability:
so that and are complementary.
By definition of conditional probability, we have
We make use of the addition rule and complementary probabilities to rewrite this as
By the law of total probability,
and substituting this into gives
This is not a right triangle as 2.6 squared plus 8.1 squared does not equal 8.6 squared (Pythagorean theorem)
It's (5,7). This is a translation. (x-4) means moving the x coordinate to the left 4 times. If it was positive it would move to the right. (y+15) moves the y coordinate to the right 15 times also would move to the left if negative.
