One of the key clinical variables that is monitored among individuals infected with COVID-19 is % oxygen saturation. Suppose we collected the following data from COVID-19 patients. Use this information to answer the the question below. Patient% Oxygen Saturation 1 2 3 4 5 6 7 8901 2 3 4 5 6 0 11 12 13 14 15 16 17 18 19 20 95 86 96 80 99 92 81 90 88 88 86 92 86 81 89 80 89 88 80 90 What is the standard deviation for % oxygen saturation among these patients? (using the normal rules for rounding, please round to one decimal point) O O 12.3 5.5 9.6 24.9 30.1

QUESTION 35 Suppose a hypertension trial is mounted and 18 participants are randomly assigned to one of the comparison treatments. Each participant takes the assigned medication and his or her systolic blood pressure is recorded after 6 months on the assigned treatment. The data are as follows. Standard Treatment Placebo New Treatment 124 134 114 111 143 117 133 148 121 125 142 124 128 150 122 115 160 128 Is there a difference in mean systolic blood pressure among treatments? Run the appropriate test at α = 0.05.

Lab 12.1 1. For Lab 12.1, use the following table to determine if there is a correlation between the price of a text book and the number of pages. The lab requires only 10 text books, so just use the first 10 entries from the table below. Pages versus Prke for Books, Type H = hardcover, S= softcover Price Type Poges 100 188 220 264 336 342 378 395 417 17 436 458 466 169 SB5 32.95 24.95 49.95 79.95 4.50 49.95 4.95 5.99 4.95 39.75 5.95 60.00 49.95 5.99 5.95 2.
