1. The following data are nitrogen content analyses performed by two different analysts on six water samples.

Water Sample Analyst 1 Analyst 2
1 32.4 28.7
2 36.0 37.5
3 43.0 40.1
4 29.8 27.0
5 59.9 57.1
6 37.6 39.7

Define di = (Analyst 1 - Analyst 2). In Questions 1 through 3, conduct the Wilcoxon signed-rank test for the test of hypothesis below:

Ho: Differences are symmetric about 0. Ha: Differences tend to be larger or smaller than 0.

Calculate the test statistic T. 2. For = 0.05, use Table 6 to specify the critical region. 3. Make a decision about Ho using information from Questions 1 and 2. 4. The following data are blood pressure readings of 16 runners before and after the Pepsi Challenge 10K:

BP before 158 149 160 155 164 138 163 159 165 145 150 161 132 155 146 159
BP after 164 153 166 161 170 142 168 166 173 151 159 167 135 160 150 170

Define di = (BP after - BP before). In Questions 4 through 6, conduct the Wilcoxon signed-rank test for the test of hypothesis below:

Ho: Differences are symmetric about 4. Ha: Differences tend to be larger than 4.

Calculate the approximate z test statistic. 5. Use the approximate z statistic in Question 4 to calculate the P-value. 6. For = 0.05, make a decision about Ho using information from Questions 4 and 5.
