The percentage of bags contain between 65 and 85 potato chips is 95%.
<u>Step-by-step explanation:</u>
A probability distribution that is symmetric and the data near the mean are more frequent than far is known as a normal distribution. Normal distributions are important in statistics and are often used to represent real-valued random variables.
The formula for finding the percentage of bags using normally distributed is given as
f(x) = (1 / sigma * square root 2 *pi) * e^((-1/2)*((x-u)/sigma))
Substituting the values of mean and standard deviation,
The percentage of bags contain between 65 and 85 potato chips is 95%.
