[R] t-stat Curve

[Isaac Barjis]

Number of subjects = 25
Mean of Sample = 77
Standard Deviation (s) = 12
sem = 2.4
df = 24

The claim is that population mean is less than 80
* > 80
So our H0 (null hupotheis) is * > 80


> qt(.95,24)
[1] 1.710882
> qt(0.05, 24)
[1] -1.710882

tstat = -1.25 on t24 falls between 1.711 (.95,24) and *1.711 (.005,24)


How Could I sketch t curve for the above data where my * would be at the center?

Best Regards
Isaac
