A study conducted in 2004 in New York City found that 212 out of 1334 participants had
hypertension. Kim ran a simulation of 100 studies
based on these data. The output of the simulation
is shown in the diagram below.
At a 95% confidence level, the proportion of New
York City residents with hypertension and the
margin of error are closest to
1 proportion ≈ .16;margin of error ≈ .01
2 proportion ≈ .16;margin of error ≈ .02
3 proportion ≈ .01;margin of error ≈ .16
4 proportion ≈ .02;margin of error ≈ .16

(co 3) the soup produced by a company has a salt level that is normally distributed with a mean of 5.4 grams and a standard deviation of 0.3 grams. the company takes readings of every 10th bar off the production line. the reading points are 5.8, 5.9, 4.9, 6.5, 5.0, 4.9, 6.2, 5.1, 5.7, 6.1. is the process in control or out of control and why? it is out of control as two of these data points are more than 2 standard deviations from the mean it is in control as the data points more than 2 standard deviations from the mean are far apart it is out of control as one of these data points is more than 3 standard deviations from the mean it is in control as the values jump above and below the mean
