A marketing research company desires to know the mean consumption of milk per week among males over age 27. A sample of 208 males over age 27 was drawn and the mean milk consumption was 3.4 liters. Assume that the population standard deviation is known to be 1 liters. Construct the 80% confidence interval for the mean consumption of milk among males over age 27.

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.

38 was the other number of your question.

your answer is #3 , 8 - 3 square root of 11
