To start, let's list what qualifies as a continuous distribution: a distribution where the random variable can take any value in an interval (or set of intervals) on the real line, with a probability density function describing probabilities over ranges rather than exact values. Option 1: T. The Student's t distribution is a classic continuous di......Login to view full explanation

You have 3 points of data with the values 1, 2 and 3. Which distribution is most likely?

Which of the following could not be probability distributions? ExampleA   ExampleB  Example C x     P(x)         x   P(x)     x     P(x) 0     .40          1   .10      50    .30 1 .    30          2    .15      60    .30                       3    .20      70     .40                       4    .15                        5    .05

True or False? Consider the following table:    x P(X=x) 0 0.32 1 2 0.20 3 0.15 4 -0.05 If P(X=1) is assigned a value of 0.38, then the above distribution is a valid probability distribution.

Q5(a). (Continued) Does this distribution meet the first requirement? Yes Does this distribution meet the second requirement? Yes Note: For the second requirement, if you sum up rounded probabilities, the sum may not be exactly what you want to have. You may allow for a rounding error of 0.01 and be lenient with this question.
