Question

MATLAB. Save the following MATLAB script in an M-file to simulate chips from

suppliers S1 and S2. Do not worry about how the script works. Run it, and based

on your output, tell which supplier you think has more reliable chips.

% Chips from suppliers S1 and S2.

%

NOS1 = 983; % Number of chips from S1

NOS2 = 871; % Number of chips from S2

NOWS1 = sum(rand(1,NOS1) >= 0.2); NODS1 = NOS1-NOWS1;

NOWS2 = sum(rand(1,NOS2) >= 0.3); NODS2 = NOS2-NOWS2;

Nmat = [ NOWS1 NOWS2; NODS1 NODS2 ]

NOS = [ NOS1 NOS2 ]

fprintf('Rel freq working chips from S1 is %4.2f.\n',...

NOWS1/NOS1)

fprintf('Rel freq working chips from S2 is %4.2f.\n',...

Answer 1

The MATLAB output is:

Command Window >> NOS1 = 983; * Number of chips from Si NOS2 = 871; $ Number of chips from S2 sum (rand (1, NOS1) >= 0.2); NODSi = NOS1-NOWS1; NOWSI = sum (rand (1, NOS2) >= 0.3); NODS2 [ NOWS1 NOWS2; NODS1 NODS2 ] = NOS2-NOWS2; NOWS2 = Nmat = NOS = [ Nosi NOS2 ] fprintf ('Rel freq working chips from Sl is $4.2f.\n',... NOWS1/NOS1) fprintf ('Rel freq working chips from S2 is $4.2f.\n', ... NOWS2/NOS2) Nmat = 773 598 210 273 NOS = 983 871 Rel freq working chips from Sl is 0.79. Rel freg working chips from S2 is 0.69.

The relative frequency working chips from S1 is 0.79.

The relative frequency working chips from S2 is 0.69.

Since the relative frequency working chips from S1 is more, we can say that the Supplier 1 has more reliable chips.

Please give me a thumbs-up if this helps you out. Thank you!
