Question

A hypothesis test yields a test statistic of z = 1.18. Compute the P-value if this is a one-tailed test and if it is a two-tailed test. O one-tailed P-value is 0.881; and two-tailed P-value is 0.4405 O one-tailed P-value is 0.119; and two-tailed P-value is 0.238 one-tailed P-value is 0.119; and two-tailed P-value is 0.0595 one-tailed P-value is 0.881; and two-tailed P-value is 1.762 Submit Question MacBook Pro 30 F3 Dll og 7 DD FB YO A & ( 3 4 5 6 7 8 9 E R T Y 0 Р

Answer 1

For one-tailed test,

P-value = P(Z > 1.18)

= 1 - P(Z < 1.18)

= 1 - 0.881

= 0.119

For two-tailed test,

P-value = 2 * P(Z > 1.18)

= 2 * (1 - P(Z < 1.18))

= 2 * (1 - 0.881)

= 2 * 0.119

= 0.238

Option - B is correct.
