How would I describe the rejection region of the test that h

How would I describe the rejection region of the test that has significant level of 0.05 and find the bower function of the test.

Let X1, X2, , Xn be a random sample 0 size 20 from a Bernoulli distribution with parameter p. In order to test the null hypothesis H0 : p 1/2 versus the alternative hypothesis H1 : p 1/2, the Likelihood Ratio Test is of the from y = x, c. Describe the rejection region of that has significant level of 0.05 and find the power function of the test.

Solution

From the sample data, the researcher computes a test statistic. If the statistic falls within a specified range of values, the researcher rejects the null hypothesis . The range of values that leads the researcher toreject the null hypothesis is called the region of rejection.

If alpha = 0.05 then if my cal statistics is greater than table value at 0.05 los then cal statistics will fall in rejection region and we will reject the null hypothesis if it is a right tailed rejection region

If alpha = 0.05 then if my cal statistics is less than table value at 0.05 los then cal statistics will fall in rejection region and we will reject the null hypothesis if it is a left tailed rejection region

Power function = 1- P(type two error) = 1 - p(Accepting H0 when H0 is not true)
