Assuming the simple probability of even A is given as P(A) and the simple probability of even B is given as P(B). Then P(A and B) yields the same answer as P(B and A).
True or False?
Answer)
True
As P(A and B) means probability of common elements of A and B
Which will be same for P(B and A)
Answer is true

In simple linear regression, a small p-value (probability for the t-value) for the slope indicates that X is not a useful predictor for Y. True or false?

a p-value represents: a) none of the given answers are true b) the probability given the null hypothesis is true, that the results could have been obtained barring the involvement of chance c) the probability, given the null hypothesis is true, that the results could have been obtained purely on the basis of chance alone d) the probability, given the alternative hypothesis is true, the results could have been obtained purely on the basis of chance alone e) the probability,...
Select the correct definition of the p-value of a test from the answer choices below: The probability that the null hypothesis is true The probability that, assuming the null hypothesis is true, we obtained a test statistic as or more extreme than what we calculated The probability that, assuming the alternative hypothesis is true, we obtained a test statistic as or more extreme than what we calculated The probability that the alternative hypothesis is false, given that the null hypothesis...
Probability: if the omega - {A,B,C} is the sample space for an experiment then P({A}) = 1/3 (True or False?) explain. if the omega - {A,B,C} is the sample space for an experiment, then P({A,B}) = 1 (True or False?) explain. if a coin is tossed three times (and it is a fair coin) then the probability that H and T each come up at least once is 3/4 (True or False?) explain.
Here is a simple probability model for multiple-choice tests. Suppose that each student has probability p of correctly answering a question chosen at random from a universe of possible questions. (A strong student has a higher p than a weak student.) The correctness of answers to different questions are independent. Jodi is a good student for whom p = 0.76. (a) Use the Normal approximation to find the probability that Jodi scores 72% or lower on a 100-question test. (Round...
1. The probability of A given B is a marginal probability. True or False 2. The purpose of hypothesis testing is to test if we have enough evidence to reject our current belief for a given scenario. True or False 3. The line of “best fit” will minimize the: A. Slope B. Y-intercept C. Sum of all the residuals D.Coefficient of correlation 4. 95% of values for a normal distribution are within 1 standard deviation of the mean. True or...
P-value is the probability, computed assuming H0 is true, that the test statistic would take a value as extreme or more extreme than that actually observed. Given the sample at hand, it is the smallest level of significance at which H0 would be rejected. It depends on the sample (hypotheses as well) and is hence also a test statistic. Generate 50 samples of size n=10 from a normal distribution with mean μ=1 and variance σ2=4. For each sample, use the...
