P (t2 to) 01, where diff 17 c. P (ts to) 005, where d -7 d. P (tsto) .05, where dif 14 EER Click the icon to view the table of critical values of t. a. The value of to is 228 b. The value of to is 2.567. c. The value of to is otio Enter your answer in the answer box and then click Check Answer. Clear All part remaining

Explanation / Answer

ans (C) degree of freedom 7 and value of t- at left tailed at 0.005 is 3.499

(d)degree of freedom 14 and value of t-at left tailed at 0.05 is 2.977 from the table od t -distribution

all given value of t can be find out with the help of T-table

USING TI84

Right Tailed t-test: 1) Calculate t_calc (t_test) 2) 2nd DISTR 3) Scroll down to tcdf( 4) ENTER 5) Now enter: t_calc, 1000, df) 6) ENTER 7) Output is the P-value

Left Tailed t-test: 1) Calculate t_calc (t_test) 2) 2nd DISTR 3) Scroll down to tcdf( 4) ENTER 5) Now enter: -1000, t_calc, df) 6) ENTER 7) Output is the P-value

Two Tailed (non-directional) t-test: 1) Calculate t_calc (t_test) 2) Find the absolute value of t_calc 3) 2nd DISTR 4) Scroll down to tcdf( 5) ENTER 6) Now enter: |t_calc|, 1000, df) 7) ENTER 8) Output is ½ of the P-value so 9) Multiply result by 2
