Discussion:
Q1: Consider the following hypothesis test:
Ho: u > 20 (( their is a line under this sine >))
Ha: u < 20
A sample of 50 provided a sample mean of 19.4. The population standard deviation is 2.
a. Compute the value of the test statistic.
b. What is the p-value?
c. Using a = .05, what is your conclusion?
d. What is the rejection rule using the critical value? What is your conclusion?
And
Q2: Consider the following hypothesis test:
Ho: u = 22
Ha: u =22 ( their is a line throw the = sine hare )
A sample of 75 is used and the population standard deviation is 10. Compute the p-value and state your conclusion for each of the following sample results. Use a = .01.
a. i = 23
b. i = 25.1
c. i = 20.
