Question 1170050
if the sample size is 15, then the degrees of freedom is 14.


yout test statistic is therefore t = -.56 at 14 degrees of freedom.


your best bet is to use a t-score calculator.


this provides you with the p-value based on the degrees of freedom indicated.


for example:


if it was a z-score of -.56, the p-value would have been .287739682.


if it was a t-score of -.56 at 50 degrees of freedom, the p-value would have been .2889899438.


if it was a t-score of -.56 at 14 degrees of freedom, the p-value would have been .2921646403.


i used my ti-84 plus to provide these values.


there are online calculators that will also do this for you.


the one i've used in the past is at <a href = "" target = "_blank">https://stattrek.com/online-calculatorhttps://stattrek.com/online-calculator/t-distribution.aspx/t-distribution.aspx</a>


here's a display of the results from using that calculator.
