Question

We asked UST employees to tell us how many megabytes of memory (RAM) they
have on their computer. We would like to test to see if the mean amount of memory
is the same for three different academic departments. We have the memory
amounts for six faculty members' machines in the three departments shown below.

the means and construct confidence interval estimates for the size of the difference
between means.

Means that do not share a letter are significantly different.
Construct a 95% confidence interval estimate for the difference between the mean
for department 1 and the mean for department 2. Start by subtracting x bar 1 from
x bar 2 to get a positive difference. You may use a t* multiplier of 2.13. Choose the
interval here that matches most closely the interval you constructed.

A researcher is interested in the affects that a person’s avatar (i.e. visual representation of oneself) has on the number of profile views on Facebook.com. The average number of individual personal profile views is known to be 230 views per day (excluding bands, artists, etc.). The researcher creates 36 fictitious profiles that contain roughly the same information but the picture (avatar) is an animated .gif of a smiling face (36 faces randomly selected from a compilation of faces judged to be of average attractiveness). The results showed that of the 36 profiles the average number of views was 250 with a standard deviation of 60. Test the hypothesis that the average number of views for a smiling face gif is significantly different than the usual number of personal profile views.

In 2010, the U.S. Congress passed the historic health care reform bill that will provide some type of coverage for the 32 million Americans currently without health care insurance. Just how widespread is the lack of medical coverage? The media claim that the segments of the population most at risk for disease and thus needing healthcare are women, children, the elderly and the poor. The following tables were generated from the U.S. Census Bureau, Current Population Survey, Annual Social and Economic Supplement (2011). The tables report the number of uninsured (in thousands) by sex, by age, and by household income. Is being insured or not dependent on gender? Fill in the degrees of freedom and p-value in the output below and draw a clear conclusion indicating which gender is more at risk of not being insured if there is a significant difference.
If 30 participants each completed a memory task three times — once each after having no, moderate, or high levels of caffeine, calculate the total degrees of freedom.
