The national average on a reading test is 72. The average for a sample of 80 students in a certain geographical region who took the exam is 70. If the population standard deviation is 12, then test the claim that the average test score for students in this region statistically different from the national average. Let LaTeX: \alphaα =5% .

State the claim: LaTeX: H_0\:\:\:\muH 0 μ ______ 72

LaTeX: H_1\:\muH 1 μ LaTeX: \ne≠72 claim

Determine the direction of the tails: Left, Right, or Two:

Find the critical value: +/-

Compute Test Point (round to 2 place values) :

Do we Reject or Do Not Reject?

Summarize: There is enough evidence to _______________ the claim.

7. In the planning stage, a sample proportion is estimated as pˆp^ = 72/80 = 0.90. Use this information to compute the minimum sample size n required to estimate p with 95% confidence if the desired margin of error E = 0.05. What happens to n if you decide to estimate pwith 90% confidence? (You may find it useful to reference the z table.
