Assuming that the selection process was done without replacement, the probability of selecting two white mugs without replacement is 1/28
<h2>Given data</h2>
Sample Space
Red mugs = 4
yellow mugs = 8
white mugs = 2
Sample Size = 4+8+2 = 14
We are going to assume the selection was done with out replacement
Hence the probability of selecting the first white mug is
<em>Pr(W1) = 2/8 = 1/4</em>
<em>The probability of selecting the second white mug is </em>
<em>Pr(W2) = 1/7</em>
<em />
Hence the probability of selecting two white mugs one after another
= 1/4*1/7
=1/28

Answer:
The answers to the questions are
(a) P = 0.0176
(b) P = 0.5
(c) P = 0.0571
Step-by-step explanation:
The P value is the calculated probability of obtaining extreme reults which are as extreme as observed res ult when the study null hypothesis H₀ is true
The p value is given by
P (
= 185 when μ = 175)
z = 
z(
= 185) = 
= 1.5811
Therefore the P ( = 185 when μ = 175) = P(z = 1.5811)
0.94295
The probability density function is
Therefore the probability is
= 0.0176
b) The type II error is given by
β = P(type II error) = P(Fail to reject the null hypothesis when it is false)
Therefore
β = P ( < 185 when μ = 185)
P
, which gives
P(z<0) and β = 0.5
(c) For true mean foam height of 195 mm we have
β = P ( < 185 when μ = 195)
and P
Which gives P(z < -1.58)
From z table the probability is β = 0.0571
Answer:
least: 4 tons, greatest: 8 tons
Step-by-step explanation:
.4 round down (5 and up, round up rule)
.7 round up
Circumference = 2πr
6.28 = 2πr
12 = 2n/3 +7n/3 -6
6.28 = 2×3.14×r
r =6.28/2×3.14
r= 1 unit
Now,
Area of a circle = πr² = 3.14×1×1= 3.14 sq.units
