We need to satisfy the random, normal, and independence conditions for these confidence intervals to be valid.
Are the requirements for constructing a confidence interval about P satisfied?Verify that the requirements for constructing a confidence interval about p are satisfied. Yes, the requirements for constructing a confidence interval about p are satisifed as the conditions of normal approximation are satified. This is because np(1-p) is greater than or equal to 10.
What are the conditions for constructing a confidence interval for P?Here are the six assumptions you should check when constructing a confidence interval:. Assumption #1: Random Sampling. ... . Assumption #2: Independence. ... . Assumption #3: Large Sample. ... . Assumption #4: The 10% Condition. ... . Assumption #5: The Success / Failure Condition. ... . Assumption #6: Homogeneity of Variances.. What requirements must be satisfied in order to calculate a 95% confidence interval?To compute a 95% confidence interval, you need three pieces of data: The mean (for continuous data) or proportion (for binary data) The standard deviation, which describes how dispersed the data is around the average. The sample size.
