Intend to calculate the first and third quartiles of a lognormal distribution with mu and sigma (two lognormal parameters) equal to -0.33217492 and 0.6065058. The expected value and the standard deviation gave me 0.8622153003153145 and 0.6191622375133721.

I intend to calculate the first and third quartiles and found this formula:

${F}^{-1}(p)=exp{\textstyle (}\mu +\sigma {\mathrm{\Phi}}^{-1}(p){\textstyle )}\text{with}0p1$

to calculate the quartiles but I didn't quite understand how to apply it and how to calculate the p-value. How can I find out the first and third quartiles of this distribution?
