A statistics practitioner wishes to test the following hypothesis: H0 : ì = 600 against H1 : ì < 600

A sample of 50 observations yielded the statistics: mean x = 585 and standard deviation sx = 45. The

test statistic of a test to determine whether there is enough evidence at the 10% significance level to reject

the null hypothesis is

(1) 2.3570

(2) 0.3333

(3) 16.6667

(4) 23.570

(5) −2.3570
