Amelting point test of n = 10 samples of a binder used in manufacturing a rocket propellant resulted in a sample mean of 153.5 °f. assume that the melting point is normally distributed with σ = 1.5°f. is it possible to conclude at 1% significance that the melting point is not 155°f? what is the value of zcalc ? report your answer in 3 decimal places.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
