Calculate the mean, standard deviation, or variance using the normal
distribution approximation of a binomial distribution.
Approximately 54% of mathematics students do their homework on time.
In a class of 250 students, what is the mean, variance, and standard deviation if we assume normality and use the normal distribution as an approximation of the binomial distribution? Answer choices rounded to the nearest whole number.
-a.)
-Mean = 54
-Variance = 8
-Standard Deviation = 62
-b.)
-Mean = 53
-Variance = 62
-Standard Deviation = 8
-c.)
-Mean = 135
-Variance = 62
-Standard Deviation = 8
-d.)
-Mean = 135
-Variance = 8
-Standard Deviation = 62
