The heights of 14 randomly selected women are given below (in inches). The sign test at the 0.1 significance level will be used to test the claim that the population median is greater than 63 inches.

66 62.3
64.4 59.6
66 63
65.5 65.8
63 66.4
63 64.2
66 63



(a) What is the value of the test statistic used in this sign test?



(b) What is the critical value in this sign test?



(c) What is the correct conclusion of this sign test?

  • There is not sufficient evidence to support the claim that the population median is greater than 63 inches.
  • There is sufficient evidence to warrant rejection of the claim that the population median is greater than 63 inches.
  • There is not sufficient evidence to warrant rejection of the claim that the population median is greater than 63 inches.
