Let's consider our cereal box example. You are the manager of the packaging process at a cereal manufacturing plant. You want
to determine if the cereal filling process is in control. The process requires no corrective action if the correct amount of cereal
per box is 368 grams with a process standard deviation is 15. To study this, you decide to take a random sample of 25 boxes,
weigh each one, and then evaluate the difference between the sample statistic and the hypothesized population parameter by
comparing the mean weight from the sample to the expected mean of 368 grams specified by the company. The sample mean is
372.5. Is there evidence that the weight is different from 368 grams?

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

(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
