Tasks Confidence interval for \mu _(WEIGHT ),\sigma estimated. Calculate the 95%\sigma 2^(nd ) group; then your group, 2^(nd ) group and 3^(rd ) group; your group, 2^(nd ) group, 3^(rd ) group and the 4^(th ) group. Does the SE decrease as the sample size increases? Report your results as \mu =\bar{x} +-SE as well as graph your answer with SE on the y -axis and n on the x -axis. Calculate confidence interval for \mu _(weight, )\sigma \sigma =13.95 95% confidence interval for the population mean weight. Did your confidence interval capture the value of population mean? t Table and t percentiles. Let t_(df.p) denote a t percentile with df degrees of freedom with a left tail area of p . Then, using the t table, determine the percentiles listed below. t_(9,90)=,t_(9,95)= t_(9,99)=,t_(9,995)=
