For a test of H0 p 050 the z test statistic equals 249 Find

For a test of H_0: p = 0.50, the z test statistic equals 2.49. Find the P-values for H_a: p > 0.50, H_a: p 0.50, and H_a: p 0.50 is The P-value for H_a: p 0.50 is The P-value for H_a: p

Solution

z = 2.49

a)

1)   p value = 0.00639

2)   p value = 0.00639*2 = 0.01278

3) p value = 0.00639

b)

NO
