For mutually exclusive events: P(A or B) = P(A) + P(B) If we have an exhaustive list of outcomes, their probabilities sum to 1.1.1. For example, the probability of getting an even or an odd number on a die. The probability of getting an even number is 363663 and the probability...
These are two false decisions, known as type 1 error and type 2 error respectively. A type 1 error, or alpha, is made when H0 is rejected, when in fact H0 is true. Alpha is the probability of saying on the outcome of a test there is an effect for the manipulation, while on ...

P(A) = 0.32 P(B) = 0.77 Calculate {eq}\rm P(A^c) {/eq}. Probability: For a given event, the chance of happening of a sub-event is referred to as the probability. The probability of the complement of an event = 1 - Probability of that event. Mathematically, we can find the ...
141 To calculate the expected value of an outcome: A. pide the value of each outcome by its probability, then add the results. B. pide the value of the desired outcome by the value all possible outcomes C. multiply the value of each outcome by its probability, then add the results D....
data, the p-value approach to hypothesis testing specifically involves calculating the p-value based on the deviation between the observed value and a chosen reference value, given the probability distribution of the statistic. A greater difference between the two values corresponds to a lower p-...
Probability and odds are similar but different. Both these concepts represent the likelihood of any event happening, directly or indirectly. With knowledge of either probability or odds, it is possible to find the other. Odds are computed using the...
We found that the probabilities of volatility clusters of an index (S&P500) and a stock (Apple) showed a similar profile, whereas the probability of volatility clusters of a forex pair (Euro/USD) became quite lower. On the other hand, a similar profile appeared for Bitcoin/USD, Ethereum/...
The test power: the probability of detecting the difference between the original rate and the variant conversion rates. Using the statistical analysis of the results, you might reject or not reject the null hypothesis. Rejecting the null hypothesis means your data shows astatistically significantdiffer...
