Assuming that the sample variances are continuous measurements, find the

the

probability that a random sample of 30

observations, from a normal population

with variance a2 = 5, will have a

sample variance of S that is between

2.766 and 7.8838

im pretty sure its

(8,15)

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

2

step-by-step explanation:

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128
