A livestock company reports that the mean weight of a group of young steers is 1157 pounds with a standard deviation of 52 pounds. Based on the model ​N(1157​,52​) for the weights of​ steers, what percent of steers weigh ​a) over 1300 ​pounds? ​b) under 1200 ​pounds? ​c) between 1000 and 1100 ​pounds?

Two samples are given. Find each sample's a) standard deviation and b) coefficient of variation. Then decide c) which sample has the higher dispersion, and d) which sample has the higher relative dispersion. A: 3, 7, 9, 7, 5 B: 10, 9, 4, 8, 3, 11, 7 D a) What are the sample standard deviations? SA (Do not round until the final answer. Then round to the nearest hundredth as needed.) Sg = (Do not round until the final answer. Then round to the nearest hundredth as needed.)

Consider a population of 800 values that are normally distributed with a mean of 80 and standard deviation of 5. What proportion of values are larger than 74? a) 0.0750 b) 0.1151 c) 0.8849 d) 0.9250

Consider the data set A (2,5,5,5,6,8) A) find the mode, median and mean. B) use the computation formula the compute the standard deviation
