Answer:
Step-by-step explanation:
Sample size = 95
X=cash carried by the persons
x bar = 8.00
s = sample std dev = 2.50
Std error =
Hence Z score would be
-0.00
b)
c) 95% conf interval margin of error = ±
=±0.54782
Confi interval = (8-0.5027, 8+0.5027)
= (7.4923, 8.5027)
C)If conf level increases, then width of interval would increase since critical value would increase.
If sample size increases std error would decrease and hence margin of error.
So interval would decrease.
Answer:
A) (7.6, 8.8)
which are the coordinates of the treasure.
Missing Problem Statement:
Given Options:
A) (11.4, 14.2)
B) (7.6, 8.8)
C) (5.7, 7.5)
D) (10.2, 12.6)
I have added the picture showing the traced map onto a coordinate plane to find exact location of treasure.
The coordinates of Tree are (16,21)
Coordinates of rock are (3,2)
Step-by-step explanation:
Let,
Coordinates of treasure be (a,b)
= distance from tree to treasure
=distance from rock to treasure
Given ratio between rock and tree, = 0.55_______(Equation.1)
which will be used to locate the treasure.
Now we just need to cross check by putting the coordinates given in the options one by one to find out value of ,
and checking if it satisfies the Equation 1.
Check (A) (11.4, 14.2)
= 14.8,
= 8.2,
= 1.8
Check (C) (5.7, 7.5)
= 6.13,
= 16.98,
= 0.36
Check (D) (10.2, 12.6)
= 12.8,
= 10.2,
= 1.25
Check (B) (7.6, 8.8)
= 8.2,
= 14.8,
= 0.55
Which satisfies Equation 1, such that ratio between rock and tree is 5:9 or = 0.55
So, the coordinates of the treasure are (B) (7.6, 8.8)
