(a) determine the null and alternative hypotheses, (b) explain what it would mean to make a type i error, and (c) explain what it would mean to make a type ii error.
18) fair packaging and labeling federal law requires that a jar of peanut butter that is labeled as containing 32 ounces must contain at least 32 ounces. a consumer advocate feels that a certain peanut butter manufacturer is shorting customers by underfilling the jars.

Null: the mean amount of peanut butter in a jar is equal to 32 oz.
alternative: the mean amount of peanut butter in a Jar is less than 32oz.

type 1 error is is rejecting the null when it is actually true. this means that we would say that the mean amount of peanut butter is not equal to 32 when it actually is.

type 2 error is failing to reject the null when it is actually false. this means that we would say the mean amount of peanut butter is equal to 32 when in reality it is less.

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
