Calculate the p-value for a hypothesis test of a proportion.
The hypotheses are H0: p=.2, H1: p≠.2, and the test statistic is z = -2.36. Use the normal distribution to calculate the p-value.
Round your answer to 4 decimal places

Hypothesis Testing, P-values: For the given alternate hypothesis (H1) and test statistic (z), determine the P-value of the test statistic. Use the answer found in the z-table or round to 4 decimal places. (a) H1: p < 0.75 The test statistic is z = −2.83. P-value = (b) H1: p > 0.85 The test statistic is z = 1.84. P-value = (c) H1: p ≠ 0.15 The test statistic is z = 1.85. P-value =
We are conducting a test of the hypotheses H0: p = 0.28 Ha: p ≠ 0.28 We find a test statistic of z = -1.45. What is the corresponding p-value? Give your answer as a proportion between 0 and 1 to 4 decimal places.
We are conducting a test of the hypotheses H0: p = 0.7 Ha: p ≠ 0.7 We find a test statistic of z = -2.08. What is the corresponding p-value? Give your answer as a proportion between 0 and 1 to 4 decimal places.
Testing: H0:p=0.42H0:p=0.42 H1:p>0.42H1:p>0.42 Your sample consists of 143 subjects, with 62 successes. Calculate the test statistic, rounded to 2 decimal places Hint: Round your ˆpp^ calculation to at least 4 decimal places before calculating the test statistic. z=z=
We are conducting a test of the hypotheses H0: p=0.2 Ha: p≠0.2 We find a test statistic of Z=2.59. What is the corresponding p-value? Round your answer to 4 decimal places.
