SOLUTION: You are performing a left-tailed t - test with test statistic t = −0.56 and a sample of size 15, find the p-value to 4 decimal places.

Question 1170050: You are performing a left-tailed t - test with test statistic t = −0.56 and a sample of size 15, find the p-value to 4 decimal places.

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 https://stattrek.com/online-calculatorhttps://stattrek.com/online-calculator/t-distribution.aspx/t-distribution.aspx

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