Assume that matched pairs of data from a poll of Internet users who were asked if they make travel plans through the Internet result in 373 positivesigns, 289 negativesigns, and 26 ties when the value of the second variable is subtracted from the corresponding value of the first variable. Use the sign test with a 0.10 significance level to test the null hypothesis of no difference.

Let 1 denote the median of the first variable and 2 denote the median of the second variable. What are the null and alternativehypotheses?

A.

H0: 1=2

H1: 12

B.

H0: 12

H1: 1<2

C.

H0: 1=2

H1: 1<2

D.

H0: 12

H1: 1=2

Find the test statistic.

Test statistic=

(Round to two decimal places asneeded.)

Find theP-value.

P-value=

(Round to four decimal places asneeded.)

Does the null hypothesis of no differencehold?

A.

Since theP-value is greater than the significancelevel, failtoreject the null hypothesis of no difference.

B.

Since theP-value is greater than the significancelevel, reject the null hypothesis of no difference.

C.

Since theP-value is less than the significancelevel, failtoreject the null hypothesis of no difference.

D.

Since theP-value is less than the significancelevel, reject the null hypothesis of no difference.
