1. Dr. Anderson and R. A. Fisher in a paper entitled "The Use of Multiple Measurements in Taxonomic Problems".

(Annals of Eugenics, 1936) found the average petal length of the iris setosa to be 1.46 cm with a standard

deviation of 0.17 cm. Find the probability that a random sample of 20 petals will have an average length of at

least 1.50 cm

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
