74 81 88 95 102 X Submit Question 109 116 123 136 Q To build a 87% CI for the mean of the population shown above, you take a random sample of 32 values. What is the Margin of Error, E? Round the Critical Value and your answer to three decimals. Note: of course, if you actually knew that the population distribution was as shown in the graph, you would not need to build a CI for the mean since it's right there in the graph. But you might use the CI to determine if perhaps the population mean has changed.
To build a Level C Confidence Interval to estimate a population mean, what would be the minimum "safe" sample size to use if you did not know that the population followed a normal distribution? Submit Question
