Omni Physical Therapy Centers is evaluating two different two different physical conditioning programs for effectiveness in reducing high pulse rates. Thirty patients are randomly assigned to program A and 25 are assigned to program B. After 4 months, program A participants showed an average pulse rate reduction of 15.2 beats per minute with a standard deviation of 4.9 beats and program B participants showed an average pulse rate reduction of 12.5 beats per minute with a standard deviation of 5.4 beats. Set up a hypothesis test to determine whether the difference in the sample means is statistically significant. Use a significance level of 5%.
I am having trouble solving this problem. Can you please provide me with some help? Thank you. I appreciate it.
