The results: 3 said their opinion of X had not changed, 8 said their opinion had changed, and 3 could not decide. What does the Sign Test at α = 0.10 imply? The sample is small -- exact binomial test is used. (This is a one-tailed test.)

1. State the hypotheses in correct notation and in keeping with the research hypothesis above.  

H0:

H1:

2. Define your choice for the test statistic S?        3. What is its observed value?

S =

S =

3. Use the Excel binomial distribution function to find the p-value of the test. Type the formula and value in the box.

p = (formula including correct arguments* here) = the value.
