A. Find the length of the iii-illlaminar condence interval. 1. {1.242 c p c 0.555 2. {1345 c p c 0.53\"} 3. D.2?5 c p c IDA-63 4. Upper condence limit = 0.820 Lower condence limit = [1.450 5. Upper condence limit = i].}'15 Lower condence limit = [1.350 E. Find the length of the confidence interval given the following data: 5. = 5.35, n= 350, condence level: 55% I. = 2.35, n: 25!}, condence level: 5595 B. = LED, n= EGG, condence level: 55% 5. s = 3.15, n: 25, condence interval: 55% 10. s = 3.25, n = 13', confidence interval: 95% t1. Solve the following problems. 11. In a group presentation, the average geometric reasoning of Grade 11 students in a Mathematics camp was observed to be El] with s standard deviation of 4. A researcher wants to replicate the studv to estimate the true population mean to within [1.5 maximum error. If the 58% level of condence is adopted, how mam.r respondents are needed? 12. Teacher Carol wants to conduct a survev about the average number of students In a certain school who wants online class instead of distance modular learning. If she plans to use 55% confidence level, 0.5 as the margin of error, and a standard deviation of 5. How manilr sample sizes does she need for the survev
