1 (50 pts). A person wants to know whether the waiting time for restaurant A is less than that of restaurant B. A sample of customers is selected from each restaurant and the results are as follows:   Restaurant A Restaurant B Sample size (n) 90 50 Sample mean (x–) 5.9 6.6 Standard deviation (s) 2.6 1.9 Using the method “7.2 Assuming Equal Variances”, at the α = 0.1 level of significance, determine whether there is evidence that the population mean waiting time for restaurant A is less than that of restaurant B.

A recent systematic review indicates that the majority of evidence suggests that phonophoresis is effective at reducing superficial pain

You choose to use ultrasound with the goals of Increase Tissue Extensibility. How much must you increase the tissue temperature?

There is high quality evidence to support using joint mobilizations to improve deficient ankle dorsiflexion resulting from a lateral ankle sprain.

You would like to achieve the ‘mild’ thermal effects of ultrasound; the tissue is superficial (~.5cm deep) and the size of the area is 2 times the ERA. What parameter settings would you use?  Please also list the target tissue temperature. 0.5 W/cm2 1.0 W/cm2 1.5 W/cm2 2.0 W/cm2 1 MHz 0.04 0.2 0.3 0.4 3 MHz 0.3 0.6 0.9 1.4 Frequency: Give a number Target Temperature (from the chart): Give a number Show the math equation with degrees per min (based on intensity)* time that gets you to the correct target temperature.

What are possible red flags for low back pain that may indicate possible serious spinal pathology? (select all that apply)

Research suggests that motor programs developed by practicing only part of a movement may not carryover to the whole task

It is important to use patient oriented outcomes because they tell you how the condition or rehabilitation effects the patient’s health related quality of life?
