Use the following sample to estimate a population mean \( \mu \). Assuming the population is normally distributed, find the \( 98 \% \) confidence interval about the population mean. Enter your answer as an open-interval (i.e., parentheses) accurate to two decimal places. \[ 98 \% \text { C.I. }= \] Estimate the population mean by finding a \( 99 \% \) confidence interval given a sample of size 42 , with a mean of \( 62.3 \) and a standard deviation of 17.5. Preliminary: a. Is it safe to assume that \( n \leq 0.05 \) of all subjects in the population? Yes No b. \( 15 n \geq 30 \) ? No Yes Confidence Interval: What is the \( 99 \% \) confidence interval to estimate the population mean? Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place. \[ 99 \% \text { C.I. }= \] Use the following sample to estimate a population mean \( \mu \).
