Transcribed Image Text: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 positive
signs, 333 negative signs, and 22 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
12 denote the median of the second variable. Wha
are the null and alternative hypotheses?
A. Ho: 1₁ #1₂
H₁:1₁ =11₂
C. Ho: 1₁ =1₂
H₁:1₁ <1₂
Find the test statistic.
Test statistic =
needed.)
OB. Ho: 1₁ 2112
H₁:1₁ <1₂
D. Ho: 1₁ =112
H₁:1₁ #1₂
