State whether the standardized test statistic t indicates that you should reject the null hypothesis. Explain.   ​(a) t=2.104 ​(b) t=0 ​(c) t=2.005 ​(d) t=−2.074                   -404t t0=2.047         A normal curve is over a horizontal axis labeled z from negative 4 to 4 in increments of 1 and is centered on 0. Vertical line segments extend from the horizontal axis to the curve at t@Sub{0}=2.047, where t@Sub{0}=2.047 is to the right of 0. The area under the curve to the right of t@Sub{0}=2.047 is shaded. ​(a) For t=2.104​, should you reject or fail to reject the null​ hypothesis?     A. Fail to reject H0​, because t>2.047.   B. Fail to reject H0​, because t<2.047.   C. Reject H0​, because t<2.047.   D. Reject H0​, because t>2.047.

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
