Question
A study anticipates that subjects treated with Drug A will have substantial improvements in their neuropathy symptoms. The researchers determine that a significance level of 5% and a power of 80% is appropriate for their test.
The hypotheses for the test are as follows:
H0: Taking Drug A does not influence neuropathy symptoms.
H1: Taking Drug A does influence neuropathy symptoms.
Suppose they gather a sample of size 30 and find a p-value of 0.06.
What should they conclude?
The researchers should conclude that they sufficient evidence to support the claim that Drug A positively influences neuropathy symptoms (p 0.05).
(enter "have" or "lack" for the first blank, and enter "<" or ">" for second blank; no quotation marks)
What type of error might they be making?
The researchers might be making a type error.
(enter: "1" or "2", no quotation marks)
Explanation / Answer
What should they conclude? answer is ( lack ,>)
The researchers should conclude that they lack sufficient evidence to support the claim that Drug A positively influences neuropathy symptoms (p > 0.05).
since p-value=0.06 is more than alpha=0.05, so we fail to reject H0 and conclude that Taking Drug A does not influence neuropathy symptoms.
What type of error might they be making? ( answer is 2)
The researchers might be making a type 2 error.
(enter: "1" or "2", no quotation marks)
type I error=reject H0| H0 is true
type II error =accept H0 | H0 is false
here researcher is accepting H0, so it might be making type II error
