15 % of spinning machine parts that manufactured by a company are defective.
If random samples o 100 parts are selected, what proportion f the samples will have
a) between 14%and 16% defective parts
b) less than 12% defetive parts
im kind of confused......because this question is including 3 parts and im not sure if it has got to do with the mean and standard deviation...
