Assume that matched pairs of data from a poll of Internet users who were asked if they make travel plans through the Internet result in 304 positive signs, 278 negative signs, and 35 ties when the value of the secon variable is subtracted from the corresponding value of the first variable. Use the sign test with a 0.05 significance level to test the null hypothesis of no difference. Let ₁ denote the median of the first variable and 12 denote the median of the second variable.

The test grades for a certain class were entered into a Minitab worksheet, and then DescriptiveStatistics were requested. The results were:MTB> Describe ‘Grades’.N MEAN MEDIAN TRMEAN STDEV SEMEANGrades 28 74.71 76.00 75.50 12.61 2.38MIN MAX Q1 Q3Grades 35.00 94.00 68.00 84.00You happened to see, on a scrap of paper, that the lowest grades were 35, 57, 59, 60, …but you don’t know what the other individual grades are. Nevertheless, a knowledgeable user ofstatistics can tell a lot about the data set simply by studying the set of descriptive statistics above.a. Write a description of what the results in the box tell you about the distribution of grades. Besure to address the general shape of the distribution, any unusual features, including possibleoutliers, the location of the middle 50% of the data and any significance in the differencebetween the mean and the median.b. Construct a boxplot for the test grades.

1) Randomly pick 5 numbers from the attached link (use a Random number generator - on Google/calculator) and say 1 - 100 and pick 5 numbers, remember, no repeats (kind of like the first discussion) then find the average of the test scores that correlate to it. This is your sample average. List your 5 numbers and write down your average. 2) The actual mean of the scores is 63.52, how off were you? The standard deviation of the data is 25.606 (think about if these are your sample statistics or population parameters). 3) Find your Margin of Error using 95% confidence. I gave you the population standard deviation so think about if it's a z-test or t-test.
An urban comminity would like to show that the incidence of breast cancer is higher in their area than in a nearby rural area. If it is found that 20 out of 200 adult women in the urban comminity have breast cancer and 20 of 300 adult women in the rural community have breast cancer, can we conclude at the 0.025 level of 1 significance that breast cancer is more prevalent in the urban comminity?
