5. Among a simple random sample of 500 of students who have taken the ACT, 219 are prepared for college mathematics. Does this represent significant evidence that less than half of the students who have taken the ACT are prepared for college mathematics upon graduation from high school? Use the a = 0.05 level of significance. The distribution of p is approximately normal since: • The sample is a simple random sample. • np. (1-po) = • The sampled values are independent of each other (n = 0.05N). Step 1: Identify the hypothesis: Step 2: The level of significance: a = 0,05 Dros
Step 3: Test statistic: Step 4: P-value = Step 5: Conclusion
