b) Null hypothesis: H0 : u1 = u2 = u3= u4  while the

Alternate hypothesis H1  : shows that all given values are equal

Step-by-step explanation:

a) Define the parameter of interest in the context

The parameter of interest in the context is the population mean

b) state The Null hypothesis and the alternate hypothesis

Null hypothesis: H0 : u1 = u2 = u3= u4  while the

Alternate hypothesis : H1 : shows that all given values are equal
