Question
The null and alternative hypotheses for a population proportion, as well as the sample results, are given. Use StatKey or other technology to generate a randomization distribution and calculate a p-value. StatKey tip: Use "Test for a Single Proportion" and then "Edit Data" to enter the sample information. Hypotheses: H0:p=0.6 vs Ha:p>0.6; Sample data: p^=5280=0.65 with n=80 Round the p-value to three decimal places. p-value =Enter your answer in accordance to the question statement the absolute tolerance is +/-0.05
Explanation / Answer
The statistical software output for this problem is:
One sample proportion summary hypothesis test:
p : Proportion of successes
H0 : p = 0.6
HA : p > 0.6
Hypothesis test results:
Hence,
p - value = 0.181
