Answer:
Step-by-step explanation:
In statistical hypothesis testing we use p values. For any test we select significance level alpha as 5% or 1% or 10%
Whenever p < alpha we reject our null hypothesis. Otherwise we accept our null hypothesis.
Hence p should be high to accept null hypothesis
Option A is incorrect
B is correct
C is wrong as p is the probability
D False
Option B is right.

Answer:
In order to calculate the expected value we can use the following formula:
And if we use the values obtained we got:
Step-by-step explanation:
Let X the random variable that represent the number of admisions at the universit, and we have this probability distribution given:
X 1060 1400 1620
P(X) 0.5 0.1 0.4
In statistics and probability analysis, the expected value "is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values".
The variance of a random variable Var(X) is the expected value of the squared deviation from the mean of X, E(X).
And the standard deviation of a random variable X is just the square root of the variance.
In order to calculate the expected value we can use the following formula:
And if we use the values obtained we got:
