For a test of population proportion H0: p = 0.50, the z test statistic equals 1.16. Use 3 decimal places.
(a) What is the p-value for Ha: p > 0.50?
(b) What is the p-value for Ha: p ≠ 0.50?
(c) What is the p-value for Ha: p < 0.50? (Hint: The p-values for the two possible one-sided tests must sum to 1.)
(d) Which of the p-values give strong evidence against H0? Select all that apply.
The p-value in (a).
The p-value in (b).
The p-value in (c).
None of the p-values give strong evidence against H0.
a) The p-value for Ha: p > 0.50
b) The p-value for Ha: p ≠ 0.50
c) The p-value for Ha: p < 0.50
d) Since all p-values are significantly large ( > 0.10), so we can say
ans-> None of the p-values give strong evidence against H0.
