Based on a poll of 1000 residents, a newspaper article claims that 62% of the residents in town favor the development of a recreational park on the west side of town. a community action group interested in preserving the environment claims that 45% of the townβs residents favor the development of a recreational park. to determine whether the sample supports the population proportion, a simulation of 100 trials is run, each with a sample of 200, using the point estimate of the population. the minimum sample proportion from the simulation is 0.46 and the maximum sample proportion is 0.76. (a) what is the point estimate of the population? (b) the margin of error of the population proportion is found using an estimate of the standard deviation. what is the interval estimate of the true population proportion? (c) the margin of error of the population proportion is found using the half the range. what is the interval estimate of the true population proportion? (d) is the community action groupβs claim likely based on either interval estimate of the true population proportion? explain.

As part of an annual fundraiser to raise money for diabetes research, diane joined a bikeathon. the track she biked on was 1,920 yards long. diane biked 38.5 laps. her sponsors agreed to donate an amount of money for each mile she biked. how many miles did she bike? first fill in the blanks on the left side using the ratios shown. then write your answer. given ratios: 5280ft / 1 mi , 1 mi /5280 ft , 1,920 yards / 1 lap , 1 lap / 1,920 yards , 3 ft / 1 yard , 1 yard / 3 ft. blanks: 38.5 laps / 1 yard x (blank) x (blank) x (blank) = (blank) miles i'm really confused on how to do this, and the explanations aren't exactly . if you could walk me through how to do this, it would be greatly appreciated.
