For this term, we will create confidence intervals to estimate a population value using the general formula: sample estimator +/- (reliability factor)(standard error of the estimator) Recall that the (reliability factor) x (standard error of the estimator)= margin of error (ME) for the interval. The ME is a measure of the uncertainty in our estimate of the population parameter. A confidence interval has a width=2ME. A 95% confidence interval for the unobserved population mean(µ), has a confidence level = 1-α...

T/F Question and explain 1.A 95% confidence interval for population mean μ is 65.6±12.8 from a sample of size n=96. If one took a second random sample of the same size, then the probability that the 95% confidence interval for μ based on the second sample contains 65.6 is 0.95. 2.The probability of a Type I error when α=0.05 and the null hypothesis is true is 0.05. 3.Because an assumption of ANOVA is that all of the population variances are...
