- The IDOLE Company has two assembly lines in its Hamburg plant. Line A produces an average of 335 units per day with a standard deviation equal to 11units. Line B produces an average of 145 units per day with a standard deviation equal to 8 units. Based on this information using the coefficient of variation determine which line is relatively more consistent? Explain the answer by the information given and through the calculations involved in arriving at the answer.Approximate the population mean and standard deviation of age for females. By the way, we find the midpoints by adding the first numbers before the hyphens in the age column and then dividing by 2 (ex: 0+10/2=5, 10+20/2=15, 20+30/2=25).An hour glass takes an average of 60 seconds to in thi of full cycle what probability of time does it take longer than 72 minutes if this dinner deviation is 5 minutes
- Suppose the linear relationship between traffic violations and auto insurance premium has SSR of 2825 and SST of 3150. What percent of the insurance premium is unexplained by traffic violation?Deer mice (Peromyscus maniculatus) are small rodents native to North America. Their adult body lengths (excluding tail) are known to vary approximately Normally, with mean μ = 86 millimeters (mm) and standard deviation o = 8 mm. Deer mice are found in diverse habitats and exhibit different adaptations to their environment. A random sample of 14 deer mice in a rich forest habitat gives an average body length of σ x = 91.1 mm. Assume that the standard deviation o of all deer mice in this area is also 8 mm. Here is the output from the TI-83 graphing calculator for a 95% confidence interval based on these findings: ZInterval (86.909, 95.291)I need to find the standard deviation of these 26 numbers
