A researcher wants to examine the impact of internet use onheart rate. Students are asked how much they used the internet thehour prior to beginning the study and then grouped into threecategories( 31-60 minutes per hour, 1-30 minutes per hour, and nointernet use.) The researcher then measured their heartbeat perminute. Assume a two-tailed test and .05 level of significance.

31-60 mins | 10 | 66.00 | 9.66092 |
1-30 mins | 10 | 54.00 | 8.43274 |
no internet | 10 | 59.00 | 7.37865 |

a) Based on the data, write up a results section. Answer shouldinclude type of analysis, variable means and standard deviations,results, significance, and effect size.
b) What are the practical implications of the results reportedin the previous question? How would you interpret these results?Consider what might impact these results or what type of studycould be done next.
