Question

Based on the number of voids, a ferrite slab is classified as
either high medium or low. Historically, 5% of the slabs are
classified as high, 83% as medium and 12% as low. A sample of 20
slabs is selected for testing. Let *X*, *Y*, and
*Z* denote the number of slabs that are independently
classified as high, medium, and low, respectively. Determine the
following. Round your answers to four decimal places (e.g.
98.7654).

(a) *P*(*X* = 1, *Y* = 17, *Z* =
3)

(b) *P*(*X* ≤ 1, *Y* = 17, *Z* =
3)

(c) *P*(*X* ≤ 1)

(d) *E*(*X*)

Answer #1

Based on the number of voids, a ferrite slab is classified as
either high medium or low. Historically, 5% of the slabs are
classified as high, 80% as a medium, and 15% as low. A sample of 20
slabs is selected for testing. Let X, Y, and
Z denote the number of slabs that are independently
classified as high, medium, and low, respectively. Determine the
following. Round your answers to four decimal places (e.g.
98.7654).
(a) P(X = 1, Y...

Based on the number of voids, a ferrite slab is classied as
either high, medium, or low. Historically, 5% of the slabs are
classied as high, 90% as medium, and 5% as low. A sample of 20
slabs is selected for testing. Let X; Y; and Z denote the number of
slabs that are independently classied as high, medium, and low,
respectively

The backoff torque required to remove bolts in a steel plate is
rated as high, moderate, or low. Historically, the probability of a
high, moderate, or low rating is 0.61, 0.25, or 0.14, respectively.
A sample of 15 bolts are selected for testing. Let X,
Y, and Z denote the number of bolts that are
independently rated as high, moderate, and low, respectively.
Determine the following probabilities.
(a)
P(X = 11, Y = 2, Z =
2)
(b)
P(X =...

People were classified as either Master or Novice chess players
based on chess playing experience. Master chess players and novice
chess players were shown chess boards and then asked to recreate
them from memory. They were first presented with a board that
contained actual game placements for 10 seconds. Then they were
given board that showed random chess piece placement for 10
seconds.
