Making conclusions based on P-value – Lesson 9.1.Assuming the large counts condition is met, use Table A to find the critical value z for a 89% confidence interval. Ob Oc z* = 1.62 z* = 1.61 z* = 1.60 ...Success/Failure Condition: There should be at least 10 expected successes and 10 expected failures in a sample in order to use the normal distribution as an approximation. Written using notation, we must verify both of the following: Expected number of successes is at least 10: np ≥ 10. Expected number of failures is at least 10: n (1-p) ≥ 10.Study with Quizlet and memorize flashcards containing terms like A teacher has two large containers (A and B) filled with blue, red, and green beads, and claims the proportion of red beads is the same in each container.

Note: In some textbooks, a “large enough” sample size is defined as at least 40 but the number 30 is more commonly used. When this condition is met, it can be assumed that the sampling distribution of the sample mean is approximately normal. This assumption allows us to use samples ...There are three conditions for performing a significance test about a proportion: Random, 10 % 10\% 10%, and Large Counts.
