Please circle T or F based on whether the following statemen

Please circle T or F based on whether the following statements arc True or False respectively. A 95% confidence interval will be wider than a 99% confidence interval. Standard error Is the same as standard deviation. We use ;3 to estimate p, because p = p. When the confidence level Increases, the sample size decreases. The sample mean follows a t distribution when the sample size is small. t distribution has the same mean and variance as the Normal distribution. The center of a confidence interval for p is X. Suppose the sample size is fixed. When the width of a confidence interval decreases, so does the confidence level.
