Answer:
a.
b-Check illustration below
c.(-0.0517,0.0177
Step-by-step explanation:
a.let 
denote processes 1 & 2.
For 
: T1=10,n1=200
For 
:T2=20,n2=300
Therefore
b. To test for hypothesis:-
i.
ii.For a two sample Proportion test
iii. for 
(0.5 alpha IS 0.025),
reject 
if
iv. Do not reject . The noncomforting proportions are not significantly different as calculated below:
z=-0.78
c.
for the p1-p2 is given as:
=(-0.0517,+0.0177)
*CI contains o, which implies that proportions are NOT significantly different.
Answer:
1/6
Step-by-step explanation:
two events need to happen: tutti frutti needs to be shown by first spinner and second spinner needs to show dish
probability of tutti frutti = 1/3
probability of dish = 1/2
probability of both events = 1/3 * 1 /2 = 1/6
Answer:
Percentage Rate=6%
Step-by-step explanation:
Total borrowed=$2,100
Time=3 years
Rate=?
Total amount owed after 3 years= total borrowed + simple interest
$2,478=$2,100 + x
X=$2,478 - $2,100
=$378
The simple interest=$378
Simple interest=P×R×T
Where,
P= principal=$2,100
R=Rate=?
T=Time=3 years
Simple interest=$378
Simple interest=P×R×T/100
$378=$2,100×R×3/100
$378=$6,300R/100
$378=$63R
R=$378/$63
R=6
Therefore,
Rate=6%
Answer:
B. Inscribed equilateral triangle.
