A livestock company reports that the mean weight of a group of young steers is 1119 pounds with a standard deviation of 81 pounds. Based on the model N(1119,81) for the weights of steers, what percent of steers weigh a) over 900 pounds? b) under 1100 pounds? c) between 950 and 1000 pounds? a) % of steers have weights above 900 pounds. (Round to one decimal place as needed.)

IQ scores are from a Normal distribution with a mean of 100 and a standard deviation of 15.  What IQ scores has a z-score of 1.20?   Group of answer choices A.) 106 B.) 95 C.) 118 D.) 82

Can you answer c,d, and e please

Analyze the following data. Assume the true value of L (the length of a table) is 93.40cm. L(cm) 93.2 93.3 93.9 92.8 93.5 93.4 92.9 a) What are the mean and standard deviation of this data sample? b) What is the uncertainty of the mean? c) Report the measured value of L. d) What is the relative discrepancy between the measured value of L and its true value? Suppose you have a second set of data for the same quantity that gives the following result: L = (93.90 ± 0.02) cm. e) Is this value more or less precise than the first value? f) Is this value more or less accurate than the first value? g) Do the two values agree given their uncertainties? h) What is the relative discrepancy between the two values?
