Question 5 (1 point) Listen A network analyst has been told that the round trip time (RTT) is 625 ms. They collect 60 readings and find that the sample mean is 678 ms and the sample standard deviation is 90 ms. If you were to test to determine if the RTT is different from 625 ms, using a 1% level of significance, which of the following combinations would be correct? Right-tailed test, with Critical value z = 2.327 and Test Stat is z=4.963 ID Two-tailed test, with Critical values z--2.575 and z-2.575, and Test Stat is z=4.562 Two-tailed test, with Critical values z--2.575 and z-2.575, and Test Stat is Z=4.164 Left-tailed test, with Critical value z= -2.327, and Test Stat is z=-4.562
