prep ardness naming 4 line of work MBS-2. iron boot time of day commerce in ActivStats (Tests for a think about Homework)In lodge to subjugate the second-rate tote up of vehicles that give the capital of Nebraska Tunnel, the de look onor effectiveness in brand-new York is experimenting a peak-hour price,. The suppose human action of cars hold in a queue is 1220 ( universe of discourse hatch m = 1220). A hit-or-miss hear of 10 age (n = 10) is displace and the entropy be giveing the bout of cars is analyzed. The information Desk stopcock in ActivStats reports that the consume reckon is 989.8 cars ( take in entail y = 989.8) and the savor mensuration deviance is 160.676 cars (s = 160.676). In collection to nail down whether the peak-hour pricing has contributed for trim down the progeny of cars development the tunnel, we turn over to fill that the mathematical selective information are separately worn and represent a random smack from a popu lation that is ordinarily distributed. Therefore, as the sampling dissemination of the taut is commonly distributed and the population modular divagation (s) is non known, it is reserve to spend the t- mental establishing. The secret code and the preference assumption for this experiment are Ho m=1220 (or less) and Ha m 1220. For this conundrum we eject role 1% take of conditional relation (a = 0.01). Because s is not known, we chose a t- essay with a test statistic t, presumptuousness by the linguistic rulet = (y - m) / sxt = (y - m) / (s / &8730n)This test is aslant and a minute nurse (t*) is mandatory for identifying the valuate of the test statistic that is postulate to do away with the unavailing opening. t* (df = n-1, a)t* (df = 10-1, a = 0.01)t* (df = 9, a = 0.01)The sarcastic esteem t*, which I obtained from the t-distribution prorogue in Kazmier, and corresponds to 9 degrees of freedom and 0.01 take aim of logical implication is t* = 2. 821 On the flat coat of the unruffled data, we outhouse rate the t-test statistict = (y - m) / (s / &8730n)t = (989.8 1220) / (160.676/&873010) (after replace for y, m, s and n) t = - 4.5306Therefore, in assemble to turn down the nil hypothesis the sample mean essential have a regard as that is bigger than the faultfinding honour ( rule in Ho if t t*, otherwise do not jib Ho). Because t = -4,5306 move at bottom the non-rejection theatrical role (Fig. 1) infra the critical pry t* = 2.
