Assume that a simple random sample has been selected and test the given claim. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim. Use a 0.01 significance level. A data set includes platelet counts (1000 cells/μL) measured from 141 adult males. In testing the claim that the population of adult males has a mean platelet count greater than 219​, the accompanying technology display is obtained.   Test of μ= 219 vs > 219   Variable    N      Mean    StDev   SE Mean  95% Lower Bound  (T)          (P) Platelet   141     223.42    64.84     5.46          212.62               (0.81)     (0.210)   Identify the value of the test statistic.   Identify the​ P-value.
