Practical 6 1. Are following statements true or false?
 

Summary: Practical 6

1. Are following statements true or false?
a) The significance level of a statistical test is equal to the probability
that the null hypothesis is true.
b) If the significance level of a test is decreased, the power of the test
would be expected to increase.
c) If a test is rejected at the significance level , the probability that the
null hypothesis is true equals .
d) The probability that the null hypothesis is falsely rejected equals to
the power of the test.
e) A type I error occurs when the test statistic falls in the rejection
region of the test.
f) A type II error is more serious than a type I error.
g) The power of the test is determined by the null distribution of the test
statistics.
h) The likelihood ratio is a random variable.

2. Poisson distribution
The distribution Poisson() with parameter > 0 is given by the probability
