What is the onesided Pvalue for a Zstat of 172 What is the t

What is the one-sided P-value for a Z_stat of 1.72? What is the two-sided P-value?

Solution

As it is positive, we get its right tailed area.

Thus,

P(x>1.72) = 0.042716221 [ANSWER, ONE SIDED]

For two sided, we just multiply it by 2,

P(two tailed of z = 1.72) = 0.085432442 [ANSWER, TWO TAILED]
