Amachine fills containers with a particular product. the standard deviation of filling weights is known from past data to be .6 ounce. if only 2% of the containers hold less than 18 ounces, what is the mean filling weight for the machine? that is, what must m equal? assume the filling weights have a normal distribution. anderson, david r.. essentials of statistics for business and economics (p. 299). south-western college pub. kindle edition.

The mean of weight is 30.3

Step-by-step explanation:

We are given the following information in the question:

Standard Deviation, σ = 6 ounces

We are given that the weights is a bell shaped distribution that is a normal distribution.

Formula:

P(container holds less than 18 ounces) = 2% = 0.02

P(x < 18) = 0.02

Calculation the value from standard normal z table, we have,  

P(Z < -2.05) = 0.02

Hence, the mean of weight is 30.3

step-by-step explanation:

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
