Two sample t test
Introduction
The research study is conducted for the purpose of checking the claim whether there is any
significant difference observed in the effects of the two treatments on the patients. For checking
this claim we have to use the stat
We are given
SS store = 0.9053
MS store = 0.4527
SS food = 1823.348
MS store = 455.8371
Total SS = 1828.058
The formula for SSerror is given as below:
SSerror = Total SS SS food SS store
Now, plug all values in the above formula and calculate the SSerror
Hypothesis Test
Suppose we are interesting in checking the claim whether the younger customers use the
ATMs more than the older customers and for this purpose we need to collect some data for
checking our claim by using the hypothesis test. So, we collect
A theoretical justification based on a certain material failure mechanism underlies the assumption
that ductile strength X of a material has a lognormal distribution. Suppose the parameters are = 5.0
and = 0.11.
(a) Compute E(X) and V(X). (Round your answ
