Step-by-step explanation:
Answer:
n = 66 (to the nearest whole number)
66 randomly selected players must be surveyed
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
x+/-M.E
M.E = zr/√n
Making n the subject of formula;
n = (zr/M.E)^2 ........1
Given that;
Mean = x
Standard deviation r = 2.7 inches
Number of samples = n
Confidence interval = 95%
z(at 95% confidence) = 1.96
Margin of error M.E = 0.65 inches
Substituting the given values into equation 1;
n = (zr/M.E)^2
n = (1.96×2.7/0.65)^2
n = 66.28464852071
n = 66 (to the nearest whole number)
66 randomly selected players must be surveyed

Well if you’re using PEMDAS I assume you’re finding what e equals?
So following (parenthesis, exponents, multiplication, devision, addition, subtraction)
e=125/24 or 5 5/24
