Question

Refer to the PairedTTest tab in the assignment spreadsheet. Note that this compares Dia 1 (before) and Dia2 (after) measurements from the same group 2.

True/False. Dia1 had a lower mean pressure than Dia2 but the measurements were much more spread out from the mean. _______

True/False. We reject Ho since p = 0.199130314. ______

Explanation / Answer

Dia1 had a lower mean pressure than Dia2 but the measurements were much more spread out from the mean.

True, because the mean pressure of Dia1 is lower than Dia2 but the variance of Dia1 is more than the variance of Dia2

We reject Ho since p = 0.199130314.

False, since the p - value is greater than level of significance so we do not reject Ho.
