The government is interested to estimate the proportion of families gathering in the weekends, in a city. The city is divided into three blocks. A stratified random sample of 60 households was selected proportionately from each block considering the blocks as strata. The summary data of the survey are presented in the following table. Stratu Ni m (i) X; Mean Si Pi 1 120 18 35.0 4.0 0.5 0.2 0.9 130 15 20.0 5.0 180 27 30.0 6.0 25 i) Estimate the proportion of family gathering in the weekend, and obtain a 95% confidence interval of your estimate. Interpret the results. ii) Find the appropriate sample size and its allocation for estimating the total family gathering, with a bound of 50 points on the error of estimation. Assume that the stratum standard deviations are o1=8, 02=12 and, o3=4. LO NO LO CO 23

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 159.11, what is the sample size of each sample?
