We wish to compare three interventions for preterm infants, with regard to effects on the infants' heart rates: Nonnutritive Sucking (NNS), Nonnutritive Sucking plus Rocking (NNSR), and Rocking (R). Nine infants are randomly assigned to six different orderings of the three treatments. Heart rate, the dependent variable, is measured after each treatment. Data can be found here: Google SheetsLinks to an external site. MS Excel fileDownload MS Excel file Use a 1% level of significance to test the claim that interventions do not influence infant heart rates. Hypotheses: (all three interventions produce equal average heart rates in the infants) (at least one intervention produces an average heart rate different than Results: p-value = (round answer to nearest hundredth of a percent - 2.35%) Conclusion: We sufficient evidence to support the claim that intervention type does influence infant heart rate (p 0.01). (Use "have" or "lack" for the first blank and "<" or ">" for the second blank.)
