In a left-hand tailed test for the population proportion, p, carried out at α = 0.05, using a large sample, the critical point is:
Here for large sample population proportion
α = 0.05
Critical value directly can be calculated from Z table or using Excel
For left tailed test:
Zcrit =Z0.05= -1.645 [From z table] {From excel =NORMSINV(.05)=-1.64485 -1.645}

1. You are performing a left-tailed matched-pairs test with 11 pairs of data. If α=.01α=.01, find the critical value, to two decimal places. 2.You wish to test the following claim (HaHa) at a significance level of α=0.10α=0.10. Ho:p1=p2Ho:p1=p2 Ha:p1>p2Ha:p1>p2 You obtain 72 successes in a sample of size n1=306n1=306 from the first population. You obtain 137 successes in a sample of size n2=633n2=633 from the second population. For this test, you should NOT use the continuity correction, and...
You are performing a left-tailed t-test with a sample size of 21. If α=.05α=.05, and your test statistic is t=−2.89t=-2.89, do you: fail to reject the null hypothesis reject the null hypothesis You will either want to either: Calculate the critical value and compare the test statistic to it. Calculate the p-value and compare it to the significance.

You wish to test the following claim (Ha Ha ) at a significance level of α=0.05 α=0.05 . Ho:p1=p2 Ho:p1=p2 Ha:p1>p2 Ha:p1>p2 You obtain 82.6% successes in a sample of size n1=447 n1=447 from the first population. You obtain 75.2% successes in a sample of size n2=472 n2=472 from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution. The test statistic's value...
