The makers of Mini-Oats cereal have an automated packaging machine that is set to fill boxes with 24 ounces of cereal. At various times in the packaging process, we select a random sample of 100 boxes to see whether or not the machine is filling the boxes with an average of 24 ounces of cereal. Which of the following is a statement of the null hypothesis?

H' : u = 24

Step-by-step explanation: Let H' represents the null hypothesis and H1 represents the alternative hypothesis.

From the question, the initial claim or assertion is that the machine is set to fill 24 ounces of cereal.

Hence H' : u = 24 ounces This is the null hypothesis.

After taking a sample of 100 boxes, they checked whether or not the machine is filling the boxes worn an average of 24 ounces of cereal.

This is the alternative hypothesis and is written as

H1: u ≠ 24 ( 2 tailed test)

x=4

step-by-step explanation:

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
