The following set of data is from a sample of n = 7 15,12,4,14,10,12,3 a) compute the coefficient of variation b) Compute the Z scores. Are there any outliers? Note: solve within 20 minutes with proper explanation.
Engineers want to design seats in commercial aircraft so that they are wide enough to fit 99% of all males. (Accommodating 100% of males would require very wide seats that would be much too expensive.) Men have hip breadths that are normally distributed with a mean of 14.8 in. and a standard deviaof 1.1 in. Find Pog. That is, find the hip breadth for men that separates the smallest 99% from the largest 196. The hip breadth for men that separates the smallest 99% from the largest 1% is Peg-. in. (Round to one decimal place as needed.)

See picture of table attached to answer, thank you Garrison Bay is a small bay in Washington state. A popular recreational activity in the bay is clam digging. For several years, this harvest has been monitored and the size distribution of clams recorded. Data for lengths and widths of littleneck clams (Protothaca staminea) were recorded by a method of systematic sampling in a study done by S. Scherba and V. F. Gallucci"The Application of Systematic Sampling to a Study of lnfaunal Variation in a Soft Substrate Intertidal Environment," Fishery Bulletin, Vol. 74, pp. 937-948). The data in Tables 8-4 and 8-5 give lengths and widths for 35 littleneck clams. (a) Use a calculator to compute the sample mean and sample standard deviation for the lengths and widths. Compute the coefficient of variation for each. (b) Compute a 95% confidence interval for the population mean length of all Garrison Bay littleneck clams. (c) How many more littleneck clams would be needed in a…
