Find which file sizes significantly differ respect to mean

Reference no: EM13142812

An experiment was conducted to test the effect of data file size on the ability to access the files (as measured by read time, in milliseconds). Three different levels of data file size were considered:small (50,000 characters),medium (75,000characters) and large (100,000 characters). A sample of eight files of each size was evaluated.

Series Small Medium Large
20 2.05 2.24 2.08
20 2.04 2.21 2.34
20 2.21 2.23 2.33
20 2.12 2.09 2.24
40 2.32 2.52 2.71
40 2.31 2.62 2.73
40 2.48 2.57 2.9
40 2.42 2.61 2.72

1. At the 5% level of significance, is there evidence of a difference among the mean access read times for the three file sizes?
2. If appropriate, use the Tukey-Kramer multiple comparisons procedure to determine which file sizes significantly differ with respect to mean access read time. Test at the 95% confidence level.
3. Specifically, what conclusions can you reach?
