In statistical process control, the hourly samples are taken. The sample means are: 156.46, 199.62, 189.31, 102.22, and 112.09 respectively. Also, the ranges of these samples are 11.97, 12.17, 13.94, 11.86, and 11.83 respectively. If the upper control limit of X-bar chart is 157.87, what is the sample size of each sample?
