The accompanying data table shows the typing speeds of 10 individuals who were measured typing using both methods.

Paired T-Test and CI: New, Traditional

Paired T for New - Traditional

N Mean StDev SE Mean
New 10 43.90 7.65 2.42
Traditional 10 39.80 5.63 1.78
Difference 10 4.10 6.05 1.91

95% CI for mean difference: (-0.22, 8.42)
T-Test of mean difference = 0 (vs not = 0): T-Value = 2.14 P-Value = 0.061

t value =2.14...........(calculated value)

t =0.061...............(table value)

since t(cal)>t(table) so we accept Ho at 95% leval of significance.

Answer :- Opetion (C=0.0606) is p value
