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 260 Americans is administered the acupuncturists treatment and 31 report experiencing migraines. a. State Hypotheses to the scenario using the correct symbols. b. What is the sample proportion? (Round to 2 decimal places) ˆpp^= c. Suppose the P-value is calculated to be 0.0427 What would your decision be for this test using α=α= 0.05? fail to reject the null reject the null

a. State Hypotheses to the scenario using the correct symbols.
b. What is the sample proportion? (Round to 2 decimal places) ˆpp^=
c. Suppose the P-value is calculated to be 0.0427
What would your decision be for this test using α=α= 0.05?
fail to reject the null
reject the null
accept the null
Write a conclusion in terms of the acupuncturist's claim. Use the model provided by the instructor. Assume no errors were made.
a).The hypothesis to be tested here is-
b). Here,
X=31
n=260
Therefore the required sample proportion is obatained as-
