A random sample of ten containers is selected, and the net contents (oz) are as follows: 12.03, 12.01, 12.04, 12.02, 12.06, 11.98, 11.97, 12.02, 12.05, and 11.99. (a) Suppose that the manufacturer wants to be sure that the mean net contents exceeds 12 oz. What conclusions can be drawn from the data (use 0 = 0.01)? (b) Construct a 99% two-sided confidence interval on the mean fill volume.

Question

4.12. A machine is used to fill containers with a liquid
product. Fill volume can be assumed to be normally
distributed. A random sample of ten containers is
selected, and the net contents (oz) are as follows:
12.03, 12.01, 12.04, 12.02, 12.06, 11.98, 11.97,
12.02, 12.05, and 11.99.
(a) Suppose that the manufacturer wants to be sure
that the mean net contents exceeds 12 oz. What
conclusions can be drawn from the data (use
a = 0.01)?
(b) Construct a 99% two-sided confidence interval
on the mean fill volume.

1. A dog groomer is often asked if small dogs bark more than larger dogs. To test this, he logs the number of separate barking episodes per day for three size dogs: small, medium, and large. In a separate file you will find the number of barking episodes for 12 dogs. On average, small dogs barked the most Mean: 7.25 On average, medium sized dogs barked the least Mean: 2.75 A. Do the different size dogs bark a significantly different number of times? Test with an α = 0.05. B. If appropriate, use Tukey’s HSD post hoc test and report where the differences are. If inappropriate, state why. C. Calculate and interpret the effect size.
