Question
A study was conducted to determine whether magnets were effective in treating pain. The values represent measurements of pain using the
visual analog scale. Assume that both samples are independent simple random samples from populations having normal distributions. Use a
0.05 significance level to test the claim that those given a sham treatment have pain reductions that vary more than the pain reductions for
those treated with magnets.
What are the null and alternative hypotheses?
OA H₂:0² +0₂2
H₁:0² = 0²/
OC. H₂:0² = 0²/2
H₁:0² #0²
Identify the test statistic.
F = 1.72 (Round to two decimal places as needed.)
Use technology to identify the P-value.
The P-value is 0.000 (Round to three decimal places as needed.)
B. H₂:0² = 0²
H₁:0² > 0²
○D. H₂:0² = 0²/
