The specifications for the baby formula sold in small bottles are: 3.000 ounces 0.150 ounces. Your company has designed a production process to fill these small bottles with the baby formula. Two hundred bottles from this process were sampled to measure the amount of baby formula. The average amount of baby formula, calculated from this sample, turned out to be 3.042 ounces (this would imply that the process average = 3.042 ounces). The standard deviation of the amounts was...

The latest model of a certain brand of electric car is reported to have an average range of 195 miles. An auto industry journalist would like to verify this claim, since she believes that the true range of the car may be less than 195 miles. The journalist selected and tested a random sample of 80 cars of this model and found that the average range of the sample was 190.8 miles with a standard deviation of 31.3 miles. Apply...

The thickness (in millimeters) of the coating applied to disk drives is one characteristic that determines the usefulness of the product. When no unusual circumstances are present, the thickness (x) has a normal distribution with a mean of 3 mm and a standard deviation of 0.05 mm. Suppose that the process will be monitored by selecting a random sample of 16 drives from each shift's production and determining x, the mean coating thickness for the sample. (a) Describe the sampling...

According to an Experian report, the average credit score for a new-car loan was 713 at the end of 2017. Suppose Ally Financial, a bank holding company that finances car loans, would like to test the hypothesis that the average credit score has increased since the Experian report. A random sample of 20 new-car loans had an average credit score of 724.2 with a sample standard deviation of 34.5. Ally Financial would like to set a = 0.05. The correct...

A phone manufacturer wants to compete in the touch screen phone market. Management understands that the leading product has a less than desirable battery life. They aim to compete with a new touch screen phone that is guaranteed to have a battery life more than two hours longer than the leading product. A recent sample of 120 units of the leading product provides a mean battery life of 5 hours and 40 minutes with a standard deviation of 30 minutes. A...
