Problem 6BSC
Assume that matched pairs of data result in the given number of signs when the value of the second variable is subtracted from the corresponding value of the first variable. Use the sign test with a 0.05 significance level to test the null hypothesis of no difference.
Positive signs: 15; negative signs: 5; ties: 7 (from a class project testing for die difference between reported and measured heights of females).

Problem 6BSC
Assume that matched pairs of data result in the given number of signs when the value of the second variable is subtracted from the corresponding value of the first variable. Use the sign test with a 0.05 significance level to test the null hypothesis of no difference.
Positive signs: 15; negative signs: 5; ties: 7 (from a class project testing for die difference between reported and measured heights of females).
ANSWER:
Solution 6BSC
The null hypothesis is the claim of no difference between the heights of the female.
H0: There is no difference between the heights of the female.
H1: There is a difference between the heights of the female.
It is given that the number of positive signs = 15
Number of negative signs = 5
Number of ties = 7
