###### Question:

A researcher wants to examine the impact of internet use on heart rate. Students are asked how much they used the internet the hour prior to beginning the study and then grouped into three categories( 31-60 minutes per hour, 1-30 minutes per hour, and no internet use.) The researcher then measured their heartbeat per minute. Assume a two-tailed test and .05 level of significance. Consider the descriptive statistics for this data.

 Time N Mean Standard Deviation 31-60 mins 10 66.00 9.66092 1-30 mins 10 54.00 8.43274 no internet 10 59.00 7.37865 Total 30 59.6667 9.64305

What would you expect from the results based on the means and standard deviations?
