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 town’s 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 group’s claim likely based on either interval estimate of the true population proportion? explain.

Someone answer asap for ! max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a. the median of max’s data is 250 b. more than half of the data points max recorded were 177 centimeters. c. a data point chosen at random is as likely to be above the mean as it is to be below the mean. d. every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
