The National Coffee Association reported that 62% of U.S. adults drink coffee daily. A random sample of 225 U.S. adults is selected. Round your answers to at least four decimal places as needed.
Required:
a. Find the mean μ.
b. Find the standard deviation σ.
c. The standard deviation σ.
Solution :
a). Percentage of the US adults who drinks coffee daily = 62%
Therefore, the mean, μ = 0.62
b). We know, p = μ = 0.62
And n = 225
Therefore, the standard deviation is given by :




c). Standard deviation, σ = 0.0324
100000000000000000000 is 6
