Use the sample data shown above to decide whether mean pulse changes after doing yoga at a = 0.01.
For correct grading, use d = before - after.
1. The population distribution requirement for this test is:
O Need a normally distributed population
O None needed
The hypotheses are:
O Ho: H1 < H2; Ha:µ1 > µ2
0> Pri :0 Z Pri O
O Ho:µ1 = µ2; Ha:µ1 # µ2
cor
O Hd = 0; µd # 0
0 < Prf :0 > Prt o
O Ho:41 2 H2; Ha:µ1 < µ2
2. This is a C twoO leftO right tailed test and the test used is a:
O 2-Sample T-Test (independent populations)
O2-Sample Z-Test (independent populations)
O Paired T-Test (dependent populations)

3. The STS (round to 3 decimals) is:
The P-value (round to 4 decimals) is:
4. The decision at a = 0.01 is:
O Do not reject Ho since P < a
O Reject Ho since P > a
O Reject Ho since P < a
O Do not reject Ho since P > a
The conclusion is:
O There is insufficient evidence to reject the claim that on average, pulse changes after yoga
O There is insufficient evidence to conclude that on average, pulse changes after yoga
O There is sufficient evidence to reject the claim that on average, pulse changes after yoga
O There is sufficient evidence to conclude that on average, pulse changes after yoga
