  1. Hypothesis Test for Proportions Z-Test for a Proportion p

  2. Conditions Random Sample *Note AP uses

  3. Standardized test statistic for a sample proportion

  4. Same –O-Same-O Steps! • Assumptions • State the null and alternative hypothesis and state the claim • Identify the level of significance • Find the test statistic - z • Find the critical value z0 and identify the rejection region OR find the p-value using normalcdf(lower, upper) • Draw conclusions about the null hypothesis and the claim and state at what level!

  5. Now do Practice 7.4! • After you finish practice 7.4 do the the technology page on 366 (1 – 3) • Now we get to 7.5 Yipee!
