2. Earlier in this chapter, we discussed that iron supplements are popular in part because they raise oxygen levels in our bodies, and increased oxygen levels help us feel more energetic. We also said that consuming an iron supplement with a drink high in Vitamin C enhances the effects of the iron supplement. A researcher has a sample of 40 people randomly assigned to two factors: iron supplement and Vitamin C consumption. Specifically, people were randomly assigned either to take an iron supplement or not to take an iron supplement. In addition, people were also randomly assigned either to consume a glass of orange juice (which is high in Vitamin C) or not to consume a glass of orange juice. The researcher uses a pulse oximetry to measure oxygen levels as the dependent variable (to keep the calculations simple, we are using intentionally hypothetical numbers for oxygen levels).The data is presented below. Carry out the analysis of variance using SPSS and determine whether there are any main effects or an interaction. Make a line graph of the results and interpret the pattern of the results.

The following table shows the ranks given by two judges to the performance of six finalists in a men’s figure skating competition:

Skater A B C D E F
Judge 1 3 5 1 6 2 4
Judge 2 1 5 2 6 3 4

a. Specify the competing hypotheses to determine whether the Spearman rank correlation coefficient is different from zero.

  • H0: ρS = 0; HA: ρS ≠ 0

  • H0: ρS < 0; HA: ρS ≥ 0

  • H0: ρS > 0; HA: ρS ≤ 0

b-1. Calculate the Spearman rank correlation coefficient rS. (Round intermediate calculations to at least 4 decimal places and final answer to 3 decimal places.)

b-2. Interpret the Spearman rank correlation coefficient rS.

  • Strong positive relationship.

  • Strong negative relationship.

  • Weak positive relationship.

  • Weak negative relationship.

c. The p-value for the test is found to be equal to 0.064. At the 5% significance level, does the Spearman rank correlation coefficient differ from zero?

  • No, since we do not reject H0.

  • Yes, since we reject H0.

  • No, since we reject H0.

  • Yes, since we do not reject H0.

Researchers at the Mayo Clinic have studied the effect of sound levels on patient healing and have found a significant association (louder hospital ambient sound level is associated with slower postsurgical healing). Based on the Mayo Clinic's experience, Ardmore Hospital installed a new vinyl flooring that is supposed to reduce the mean sound level (decibels) in the hospital corridors. The sound level is measured at five randomly selected times in the main corridor.
