True or false: Approximately 95% of the sample data values will be contained within the confidence interval. Why?
Homework Answers
Answer - FALSE
A confidence interval is a type of interval estimate for unknown population parameter. A confidence interval at 95% means we are 95% confident that the true population mean contains within that interval.

To compute a t statistic, you must use the sample variance (or standard deviation) to compute the estimated standard error for the sample mean. True False The 95% confidence interval for the difference between two treatment means extends from-2.50 to +5.50. Based on this information, you can conclude that there is no significant difference between the treatments at the .05 level of significance True O False

a.) The margin of error in a 95% confidence interval for the true mean of a population is 2.5, based on a random sample of 100 measurements. If the sample mean is 27.5, the 95% confidence interval must be b.) In a random sample of 100 measurements from a population with known standard deviation 200, the average was found to be 50.

Explain what "95% confidence" means in a 95% confidence interval. What does "95% confidence" mean in a 95% confidence interval? A. If 100 different confidence intervals are constructed, each based on a different sample of size n from the same population, then we expect 95 of the intervals to include the parameter and 5 to not include the parameter. B. The probability that the value of the parameter lies between the lower and upper bounds of the interval is 95%....
