Truth p ~ Two samples are drawn to test the hypothesis, H0: p = 0.5 vs HA: p <0.5H0: p = 0.5 vs HA: p <0.5 n1=n2=123n1=n2=123
Consider the statement:
The samples will produce different p-values for the hypothesis test above.
Is this statement always true, sometimes true or never true?
If no. of successes i.e. x is same for two samples then the sample proportions are same and hence the samples will produce same p-values otherwise the samples will produce different p-values. Since no. of successes may not be same always so this statement is sometimes true.

Truth p ~ Two samples are drawn to test the hypothesis, Ho : p = 0.5 vs HA: p < 0.5. Both samples have the same size ni = n2 = 123. However, the samples yield different sample proportions. Consider the statement: Both samples will produce the same p-value for the hypothesis test above. Is this statement always true, sometimes true or never true?
Truth p~ Two samples are drawn to test the hypothesis,Ho: p= 0.5us H4: p0.5. One sample has size n 250 and the other has size n=125. Both samples yield the same sample proportion of 0.4.Consider the statement:The samples will produce the different p-values for the hypothesis test above..

onsider the hypothesis test below. H0: p 1 - p 2 ≤ 0 Ha: p 1 - p 2 > 0 The following results are for independent samples taken from the two populations. Sample 1 Sample 2 n1 = 200 n2 = 400 p1 = 0.23 p2 = 0.16 What is the value of the test statistic (to 2 decimals)? What is the p-value (to 4 decimals)? With α = .05, what is your hypothesis testing conclusion?
Consider the following hypothesis statement using a = 0.01 and data from two independent samples: H0: U1 - U2 > 0 H1: u1 - u2 < 0 X1 = 122 X2 = 139 1 = 39 2 33 n1 = 40 n2 = 45 a. Calculate the appropriate test statistic and interpret the result. b. Calculate the p-value and interpret the result.
If we are testing the hypothesis H0: p = 0.5 vs. H1: p > 0.5 where p represents the proportion of American adults who would not be concerned if NSA collected records of personal telephone calls. When would you conclude that the data provide enough evidence that the proportion of adults who would not be concerned is 0.5? A. Never B. When exactly half of the people in the sample say they would not be bothered. C. When the 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
