Question 1175231: The proportion of Americans who have frequent migraines is 15.2% according to the CDC. An acupuncturist claims that her treatment can reduce this figure significantly. A random sample of 400 Americans is administered the acupuncturists treatment and 48 report experiencing migraines.
1. Suppose the P-value is calculated to be 0.0135
What would your decision be for this test using α = 0.025?
fail to reject the null
accept the null
reject the null
2. Write a conclusion in terms of the acupuncturist's claim. Use the model provided by the instructor. Assume no errors were made.

Hi
Ho:  p = .152
Ha:  p < .152 claim
p-value = .0135
α = 0.025
1) .0135 < .025, reject the null
2) There is sufficient evidence at the 0.025 level of significance to support the claim by the acupuncturist  that her treatment can reduce this figure significantly.
Wish You the Best in your Studies.
