Refer to the data set of 20 randomly selected presidents given below. Treat the data as a sample and find the proportion of presidents who were taller than their opponents. Use that result to construct a 95% confidence interval estimate of the population percentage. Based on the result, does it appear that greater height is an advantage for presidential candidates? Why or why not? Click the icon to view the table of heights. Construct a 95% confidence interval estimate of...

An IQ test is designed so that the mean is 100 and the standard deviation is 17 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 90% confidence that the sample mean is within 6 IQ points of the true mean. Assume that o = 17 and determine the required sample size using technology. Then determine if this is a reasonable sample...

For a certain law school, the entering students have an average LSAT score of about 700 with a standard deviation of about 40. The smoothed density histogram of the LSAT scores appears to follow a normal distribution. Sketch a smoothed density histogram (a bell-shaped curve) of the distributions for the LSAT scores. (For this problem, draw this on your own paper. You will not need to submit this graph.) Because this distribution is approximately normal, the mean is equal to...
