A hypothesis test for a population proportion p is given below:
Ho: p = 0.25 vs. Ha: p NE 0.25 (NE means not equal)
For sample size n=100 and sample proportion p = 0.30, compute the value of the test statistic:
1.67
-1.12
0.04
1.15
solution:
H0 : p =0.25
Ha : p 0.25
= 0.30
P0 = 0.25
1 - P0 = 0.75
Test statistic = z
= - P0 / [P0 * (1 - P0 ) / n]
= 0.30-0.25/ [(0.25*0.75) / 100]
= 1.15

Perform the following hypothesis test of a proportion: HO: p = 0.33 HA: p not equal to 0.33 The sample proportion is 0.31 based on a sample size of 100. Use a 10% significance level. A) What is the value of the test statistic? (Give answer rounded to 2 decimals) (be careful to make sure your + or - sign is correct) B) What is the p-value for the problem? C) should the null hypothesis be rejected? YES or NO
Hypotheses and summary sample statistics are given for a test for a proportion. Test Ho : p = 0.3 vs Ha :p>0.3 when the sample has p = 0.37 and n = 500. Find the value of the standardized z-test statistic and then use the standard normal distribution to find the p-value. Round your answers to three decimal places. z-test statistic - p-value = What is the conclusion using a 5% significance level? O Reject Ho O Do not reject...
Given the null and alternative hypotheses below, test the hypothesis using a = 0.01 assuming that a sample of n = 200 yielded x = 106 items with the desired attribute. Ho p20.59 HA P<0.59 Check the requirement for a hypothesis test for a proportion In this situation, np is (Type integers or decimals.) 5 and n(1-P)= 75. Thus, the requirement satisfied What is the test statistic? z= (Round to two decimal places as needed) What is the p-value? p-value...
5. Consider testing the hypothesis Ho : p = 0.5 vs. Ha : pメ0.5 using two tests, both at the same level of significance. The first test, Tl, requires a sample of size 45 while the second test, T2, requires a sample of size 100 for their power functions to be equal at the particular alternative p 0.3. What is the efficiency of T2 relative to T1? Ffficiency (ARE) of test Tı relative to test T2 is 0.3 and the
