1. On average, per bag of banana crackers is 240g but someone complained that there's less mass. 101 bags were reviewed and mass (m grams) were written as: Sum of m = 24125.8 Sum of m^2 = 5766435.5 i. for population mean, standard deviatiun of m, find unbiased estimates (up to 3 decimals). ii. try at 5% significance level if 240g is overestimated. iii. 10% of the bags is low quality when mass is below 240g. Find min. and max. amount of low quality bags when there are 100 bags examined so that the claim of 10% will not be returned in 2 tailed test with 2% significance level. 2. delayed bus arrivals has normal distrubution w/ mean 15mins & standard dev. L minutes. 97% delayed for below 20mins. i. find standard dev. L minutes (up to 2 decimals). ii. find probability that mean time of random 15 arrivals have delayed 13-17 mins. 1.
