00:01 So in the x percentile represents the data value that has percent of all data values and for 91 percent of all data so we have the percentile below 91 percentile so we have the area given that is equal 91 percent represent it as in decimal so we have 0 .9100 in this the z score table on the statistical table of normal distribution core of cdf or central density function and we have seen that or is community density function we have seen that our 0 point i think is stable from the area of 0 .910 is near at 1 .3 as this density community frequency that is equals to 0 .9099 so here the z score of 91 % is about 1 .9 % is about 1 .9.

02:06 30 the next is letter v that is given that is equals the percentile 9 percent on the table 0 .3 the value of the 0 .9 percent is about negative or not for it's a first we represented as decimal which can see the completed distribution frequency that is negative 1 .30 that is equals to 0 .0 .091 it is near 4 % so the this score is this one is equals to negative 1 .30 then we have another given that is letter c that is 75 % percent percentile so represent it on the same one so you have zero point 75 looking on the normal distribution standard or not standard normal cdf we have at 0 .075 then we can see that we can see if that it's about from 0 .68 and between 0 .68 and 0 .67 so we have so yet it's between in the twin death so we have the score of j equals to 0 .675 other one is about 25 percentile we express it as decimal so we have 0 .25 the table 8 .3 the standard normal core areas we have the value 0 .25 and this is at between negative 6 point or negative 0 .67 and it's negative 0 .68 so on that between so so we have day that is equals to negative 0 .675 and the other one the sixth percentile so have six percentile so the six percent represent it as decimal point so we have zero point zero point six though in the table four point eight value of zero point zero six is about zero 0 .06 0 .2 negative 2 .51 no that's that it's about about j that is equals to pamp for negative 1 .55 that is about 0 .0606 the z of negative 1 .60 that is equal to 0 .59 to 4 or we have 56 this one is 56 0 .594 or we have 0 .0 .0 .594 or we have 0 .0 .5...
