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
Answer:
4m
Step-by-step explanation:
shapes are similar.
purple shape is double the red and 2x2 is four
so the answer is 4m
Li can expect to roll a one 4 times.
Since there are six possibilities (1, 2, 3, 4, 5 & 6), you divide 24 and 6 to get 4.
