Question

Data is collected to perform the following the hypothesis test:

H0: µ = 5.5
Ha: µ ? 5.5.

The sample mean of the data is y = 5.4 and the P-value is .1034. Select the choice below that gives the proper interpretation of this P-value.

a) If the null hypothesis is false, then the probability of obtaining a sample mean closer to 5.5 than 5.4 is .1034.

b) The probability that the sample mean y differs significantly from 5.5 is .8966.

c) The probability that the null hypothesis H0 is true is .8966.

d) The probability that we have made a mistake is .1034.

e) The probability that the null hypothesis H0 is true is .1034.

f) If the mean µ does not differ significantly from 5.5 (that is, if the null hypothesis is true), then the probability of obtaining a sample mean y as far or farther from 5.5 than 5.4 is .1034.

g) The probability that the alternative hypothesis Ha is false is .1034.


As a quick check to determine whether the mean nicotine content per cigarette µ of the Dy2Soon brand is greater than the advertised value of 1.7 milligrams, a health advocacy group selects a random sample of 10 Dy2Soon cigarettes and uses the resulting nicotine content data to test

H0: µ = 1.7
Ha: µ > 1.7

The calculated value of the test statistic is t = 1.98.

Question 1.
Is the result significant at the 5% level (that is, a = .05)? (Don't guess; only 1 submission allowed).

YES or NO???

Question 2.
Is the result significant at the 1% level (that is, a = .01)? (Don't guess; only 1 submission allowed).

YES or NO???

Explanation / Answer

for the yes and no questions (second question) the answers are YES; NO
