The Illinois State Toll Highway Authority is conducting a study to estimate the mean one-way distance to work for likely toll-road commuters. The study researcher desires a 3-mile margin of error at 90% confidence. The population standard deviation is unknown, so a best guess is used as the planning value for o. The highway authority estimates that the smallest distance to work in the population of low-income consumers is 3 miles, and the largest distance to work is 90 miles. A rough approximation of the population standard deviation is Use the Distributions tool to help to answer the question that follows. Select a Distribution Distributions 0 1 2/3 To satisfy the requirement for the margin of error, a sample size no smaller than is needed.

1. Measure your height and find how many standard deviations you are from 50th percentile using the Anthropometry table in slide 17 in the Anthropometry slides. My height is 5 feet 7 inches. 2. Using this measured stature, estimate the lengths of your forearm, foot, and hand (https://exrx.net/Kinesiology/Segments). 3. Measure your forearm, foot, and hand using a tape measure (or some other device).( forearm= 7inches; foot=10inches; hand=22inches). 4. Indicate the error in %s for each segment (compare measured vs table value), and indicate which if your 3 segments was the furthest off.
