Suppose X is random variable that follows a Normal Distribution with mean = 10, and standard deviation = 2. What is the probability that 4 ≤ X ≤ 16? (Please type your answer in numerical numbers, not in percentages. For example, use 0.1234, instead of 12.34%.)

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x
