Question 1198099
Normal Distribution: µ =2.3mo and σ = 1.1
Sample of 50:   x̄ = 1.9mo
6) test statistic = z = {{{z =blue( (1.9-2.3) )/blue(101/sqrt(50))}}} = -2.5713
7) p(-2.5713) = normacdf(-9999, -2.5713, 1, 0) = .0051
8) which of the following statements about the significance of this study 
at a 0.05 level is correct?
 C) The p-value of the test value is less than .05 it is significant. 
 Significant, in that, the Evidence indicates the claim µ =2.3mo be rejected.
