A statistics practitioner formulated the following hypothesis: H0 : ¦Ì = 200 against H1 : ¦Ì < 200 and
learned that x = 190 n = 9 and ¦Ò = 50.
The pvalue of the test is
(1) 0.6
(2) 0.2743
(3) 0.7743
(4) −0.2743
(5) Cannot be found with information given
My suggested solution is answer 5 as i calculated pvalue to equal 0.2826
Pretty please check ASAP

Check again. Based on the ztest statistic, I see (2) as the pvalue.
