The probability is![P(X \le 0.305 ) = 0.01795](/tpl/images/0721/5445/91c76.png)
Step-by-step explanation:
From the question we are told that
The population mean is![\mu = 0.966 \ grams](/tpl/images/0721/5445/0189c.png)
The standard deviation is![\sigma = 0.315 \ grams](/tpl/images/0721/5445/76527.png)
Given that the amounts of nicotine in a certain brand of cigarette are normally distributed
Then the probability of randomly selecting a cigarette with 0.305 grams of nicotine or less is mathematically represented as
Generally
So
From the z-table(reference calculator dot net ) value of![P(Z -2.0984 ) =0.98205](/tpl/images/0721/5445/d0476.png)
So
=>![P(X \le 0.305 ) = 1 - P(X 0.305) = 0.01795](/tpl/images/0721/5445/35e65.png)
=>![P(X \le 0.305 ) = 0.01795](/tpl/images/0721/5445/91c76.png)
