Ophthalmology Retinitis pigmentosa (RP) is a hereditary ocular disease in which patches of pigment appear on the retina, potentially resulting in substantial vision loss and in some cases complete blindness. An important issue is how fast the subjects decline. Visual fields is an important measure of area of vision which is measured in degree ^ 2. The visual field for normal person is around 11,000 degrees ^ 2. The longitudinal data in table 11.31 were provided by an individual patient. Suppose the rate of change of In (visual field) is a linear function of follow-up time.
Question:
What does the intercept mean in this context? What is the estimated percent decline in visual field per year?
A manager of a small store wanted to discourage shoplifters by putting signs around the store saying "Shoplifting is a crime!" However, he wanted to make sure this would not result in customers buying less.
Compute test statistic and p -value for each sample. (Negative amount must be pointed out by minus sign.)
If a pregnancy length is randomly taken from this distribution, what is the probability that the length of that pregnancy is less than 260 days?
Suppose that you perform a significance test regarding a population mean and that the evidence does not warrant rejection of the null hypothesis.
Suppose that the distribution of weekly water usage for single-family homes in a particular city is mound shaped and approximately symmetric. The mean is 1400 gallons, and the standard deviation is 300 gallons.
Calculate a 95% confidence interval for the population mean, based on the sample 10, 12, 13, 14, 15, 16, and 49.
Using the dataset, produce a graph of per capita GDP for Argentina, China, and Canada from 1965 to 1995. Is inequality between these countries increasing?
Explain finding value of test statistic and P-value also understand the result. At the .01 significance level can we compute that the mean fare has increased.

Perform a posthoc test that is suitable if we assume that group 7 is a control group and that the other are different treatment groups and that we are only interested in finding significant treatments, not to compare them.
Tom works the night shift at a gas station on the edge of Champaign. One night he mixed 3 stale doughnuts in with 13 fresh doughnuts. That night 6 customers bought one doughnut each, selecting them at random. What is the probability that at least ..
