Based on a very large sample, it was found that 10 percent of the loaves weighed less than 15.34 ounces, and 20 percent of the loaves weighed more than 16.31 ounces. What are the mean and standard deviation of the distribution of the weights of the loaves of bread? A. μ = 15.82, σ =.48
B. μ = 15.82, σ =.69
C. μ = 15.87, σ =.50
D. μ = 15.93, σ =.46
E. μ = 16.00, σ =.50
