5. Do left-hand and right-hand average reaction times differ? To test this, 12 right-handed subjects were randomly selected and the reaction times of their right and left hands, in thousands of seconds, were recorded. The following table contains the results.

Subject 1 2 3 4 5 6 7 8 9 10 11 12 Right 189 96 112 166 115 131 169 158 110 102 182 157

Left 222 168 188 205 195 168 178 169 138 186 152 218

At α = 0.10, test the claim that there is a difference in the average reaction times of the left and right hands. Use the p-value method.

Results from five of the students are included in the graph to the right.

When subjects were treated with a​ drug, their systolic blood pressure readings​ (in mm​ Hg) were measured before and after the drug was taken. Results are given in the table below. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Using a 0.05 significance​ level, is there sufficient evidence to support the claim that the drug is effective in lowering systolic blood​ pressure? Before 189 175 188...

3.53 The time from when a patient is discharged from North Shore Hospital to the time the discharged patient’s bed is ready to be assigned to a new patient is referred to as the bed assignment turnaround time. If the bed turnaround time is excessive, it can cause problems with patient flow and delay medical procedures throughout the hospital. This can cause long waiting times for physicians and patients, thus creating customer dissatisfaction. The admissions RN has assigned a patient...
