Question
use a t-test to test the claim about the population mean ? atthe given level of sign ance ? usingthe given sample statistics. Assume the ulation is normaly Clam: ? . 51,500, a-oo! Sample statistics: x-51,672, s-2400, n 19 Click the loon to view the t-distribution table What are the null and altemative hypotheses? Choose the correct answer below. OA. Ho: ? 251,500 HO ? , 51,500 ?-51,500 ?#51,500 H. ?#51,500 ? B. "-: ? 51,500 What is the value of the standardized test statistic? The standardized test statistic isRound to two decimal places as needed) What isare) the critical value s)? Click to select your answerls). 2 3 5Explanation / Answer
ho: u1=u0
h1: u1 and u2 are not equal
b)
t = (u1-u0)/(s/sqrt(n))
(51.672-51)/2400/sqrt(19)
=0.001
at n-1 = 18 degrees of freedom t ~1.8
so we fail to reject the null
u1=u0
