Answer:
-2.2 (-2.2124%) is the answer as -2.2124^2 = -4.89% is found first below. -2.2124 is part of the derivation equation to find the relation with z.
z<-1.05 therefore = -2.2<-1.05
Step-by-step explanation:
-4.89%
-0.27631578947 x 74= -20.4473684208
P)z<-105) = 100/-20.4473684208 = -4.89060489067 less than the population of 100%
0 = population standard deviation = 3.8 we divide from 1.05
(in normal derivation questions we can multiply before dividing 0 key letter =(z- u)^2 / divide all by N) This is why we divided.
N = the size of the population = 100/D we used 100/D to find the first part.
z = each value from the population = z<-1.05
u = the population mean = 74 we multiplied second step after first step 3.8 we divide from 1.05
So that 1.05/3.8 = -0.27631578947 x 74 = D
We then Divide into N = 100/D
to find a whole or a percentage.
= -4.89
z = -2.2
