Answer:
<h2>
$5.03</h2>
Step-by-step explanation:
Given data
Sample Mean (M): $48.77
Sample Size (n): 20
Standard Deviation (σ) : $17.58
Confidence Level: 80%
we know that z*-Values for 80% Confidence Levels is 1.28
the expression for margin of error is given bellow\
MOE= z*σ/√n
We can now substitute into the expression and solve for the MOE as
MOE= 1.28*17.58/√20
MOE= 22.502/4.47
MOE= 22.502/4.47
MOE= 5.03
The margin of error for a 80 % confidence interval is $5.03
So about 2 inches or 5 inches
convert the feet to inches. then multiply all 3 numbers to get your answer
1.7 feet = 1.7 x 12 = 20.4 inches
19 x 20.4 x 6 = 2325.6 cubic inches
18 is 60+35=95 180-95= 85 so ?=85°
