A study records the hemoglobin levels in grams per deciliter of 1010 athletes: 12.912.9, 13.313.3, 14.214.2, 14.714.7, 12.412.4, 13.913.9, 14.514.5, 12.612.6, 14.014.0, 12.712.7. Use the Wilcoxon signed-ranks test at a 0.010.01 significance level to test the claim that athletes have a median hemoglobin level of 13.513.5 grams per deciliter. Assume that the population of differences has an approximately symmetric distribution.

Problem 176Multiple Choice

A study records the hemoglobin levels in grams per deciliter of $10$ athletes: $12.9$ , $13.3$ , $14.2$ , $14.7$ , $12.4$ , $13.9$ , $14.5$ , $12.6$ , $14.0$ , $12.7$ . Use the Wilcoxon signed-ranks test at a $0.01$ significance level to test the claim that athletes have a median hemoglobin level of $13.5$ grams per deciliter. Assume that the population of differences has an approximately symmetric distribution.

There is insufficient evidence to warrant rejection of the claim that athletes have a median hemoglobin level of $13.5 g slash dL$ .

There is sufficient evidence to warrant rejection of the claim that athletes have a median hemoglobin level of $13.5 g slash dL$ .

There is insufficient evidence to support the claim that athletes have a median hemoglobin level less than $13.5 g slash dL$ .

There is sufficient evidence to support the claim that athletes have a median hemoglobin level less than $13.5 g slash dL$ .
