A potato chip manufacturer has two packaging lines and wants to determine if the variances differ between the two lines. They take a sample of n= 15 bags from each line and find the following:
s1 = 0.09 ounces s2 = .06 ounces
The value of the test statistic is F = 1.5
A) True B) False
Homework Answers
Solution :
s1 = 0.09
s21 = 0.0081
s2 = 0.06
s22 = 0.0036
Test statistic = F
= s 22 / s 12
= 0.0081 / 0.0036
Test statistic = F = 2.25
B) False

A potato chip manufacturer wants to produce bags that open easily, without tearing the inner lining of the bag. In an attempt to reduce tears, the manufacturer adjusts the width of a bag's seal, either increasing or decreasing seal width by some number of millimeters. The manufacturer produces 19 different bags and measures the degree to which each bag tears (in millimeters). A statistician at the company then estimates the following regression equation. Question 4 [30 Points] -b+m Change in...

9. A potato chip manufacturer claims that the weights of its potato chips are normally distributed with a mean of 10 ounces per bag. The Department of Consumer Protection takes a random sample of 23 bags of potato chips from a shipment to test whether or not they really weigh 10 ounces. If the sample has mean weight of 9.85 ounces and standard deviation of 0.3 ounce, can you conclude that a bag of potato chips does not weigh 10...

A potato chip company makes potato chips in two flavors, Regular and Salt & Vinegar. Riley is a production manager for the company who is trying to ensure that each bag contains about the same number of chips, regardless of flavor. He collects two random samples of 10 bags of chips of each flavor and counts the number of chips in each bag. Assume that the population variances of the number of chips per bag for both flavors are equal...

A manufacturer of mountaineering equipment produces traditional three-strand climbing rope on two separate production lines, line 1 and line 2. The manufacturer regularly tests the tensile strength of its ropes by randomly selecting ropes from production and subjecting them to various tests. The results from the most recent random sample of ropes are shown below. Assuming the population of tensile strengths for each line is approximately normally distributed with equal Line 1 Line 2 variances, can the manufacturer conclude there...

A pet food producer fills 25-pound bags of dog food on two different production lines located in separate cities. In an effort to determine whether differences exist between the average fill rates for the two lines, a random sample of 17 bags from line 1 and a random sample of 22 bags from line 2 were recently selected. Each bag's weight was measured and the accompanying table reports the summary measures from the samples. Assume the two lines are normally...

QUESTION 2 A company that manufactures electronic components wants to evaluate the following hypothesis test, using a level of significance of 0.1. A random sample of 15 components was taken; 9 were tested at 80° F (X1), and 6 were tested at 120° F (X2). The results are given below S1 =40, S2 =30 If the null hypothesis is true, what is the distribution of the test statistic? t distribution with 9 degree of freedom t distribution with 11 degree of...

Two different models of a car manufacturer are compared to see if Model A has a higher average miles per gallon (mpg) than Model B. A sample of size 14 Model A cars found a sample average of 28.2 mpg and a standard deviation 3.0 mpg. A sample of size 10 Model B cars found a sample average of 22.6 mpg and a standard deviation of 5.1 mpg. Conduct the appropriate hypothesis test. a. Ho: μA = μB Ha: μA...
