Question
For each problem, select the best response. a) The hypothesis H_0: p = 0.25 H_a: p > 0.25 was tested using a level of significance of 0.05. The result of the test was to reject the null hypothesis. Which if the following statements must be false? the sample proportion was greater than 0.25 the p-value was close to zero the p-value was less than 0.20. the test statistic was negative (b) The hypothesis H_0: p = 0.60 H_a: p > 0.60 was tested using a level of significance of 0.05. The result of the test was to fail to reject the null hypothesis. Which if the following statements must be false? the p-value is less than 0.01 the sample proportion was less than 0.60 the test statistic was negative the sample proportion was greater than 0.60 (c) The hypothesis H_0: mu = 100 H_a: mu notequalto 100 was tested using a level of significance of 0.05. The sample mean was 109 and the result of the test was to fail to reject the null hypothesis. Which if the following statements must be false? the p-value is less than 0.10 the test statistic was negative the test statistic is positive The p-value is greater than 0.01Explanation / Answer
1 a) option D is correct (as it is right tailed test and critical region on positive side)
b)option A is correct (as for fail to reject p value can not be less then 0.05.)
c)option B is correct ( as test stat =(109-100)/std error which is positive)
