Homework Answers
Ans:
8)The above statement is False.
Test statistics are calculated based on the information collected from the sample.
9)The above statement is False.
As,normal distribution will have different probability at each individual value of X,as its probability density function is bell shaped.
10)The above statement is True.
We take inference from the sample data and then calculate test statistics,then we conclude and generalize for population.

Suppose that the null hypothesis is true, that the distribution of the test statistic, say T, is continuous with cumulative distribution function F and that the test rejects the null hypothesis for large values of T. Let V denote the p-value of the test. a. Show that V = 1 − F(T). b. Conclude that the null distribution of V is uniform. c. If the null hypothesis is true, what is the probability that the p-value is greater than 0.1?
