Answer:

He should buy two of the 5-pound bag.

Step-by-step explanation:

The cook needs 10 pounds of flour.

He wants to spend the least amount of money.

First option is a 5-pound bag for $2.89 each.

He can get 2 of the 5-pound bag which equals 10 pounds of flour for 2 x $2.89 = $5.78

Second option is a 2-pound bag for $1.59 each.

He can get 5 of the 2-pound bag which equals 10 pounds of flour for 5 x $1.59 = $7.95.

Second option is $2.17 costlier than the first option.

So, he should go for 2 of the 5-pound bag in order to spend the least amount of money while shopping for 10 pounds of flour.

x = 31 - 17

x = 14

Every time you conduct a hypothesis test, there are four possible outcomes of your decision to reject or not reject the null hyp

almond37 [142]

Answer:

1. A. You allow the passenger to board his flight when the passenger has a weapon.

2. B. You select the passenger for further inspection when the passenger has no weapon.

Explanation:

1. Remember, a Type I error in simple words means that the assumption "the passenger has a weapon" (null hypothesis) is actually true, but the airport security screener incorrectly concluded it is false. In other words, he assumed the passenger had no weapon and allowed the passenger to board his flight when he actually did have one.

2. While, a Type II error means that the assumption "the passenger has a weapon" (null hypothesis) is actually false, but the airport security screener incorrectly concluded it is true. In other words, he assumed the passenger had a weapon and selected the passenger for further inspection when he actually didn't have one.
