From the given data
Test Statistic F = 0.0837^2 / 0.329^2 = 0.064723
Test Statistic, F: 0.0648
Lower Critical F: 0.1041176
Upper Critical F: 9.60452
P-Value: 0.0213
Here P-value < alpha 0.05 so we reject H0
Correct answer: YES

Sample To determine the organic material in a dried lake bed, the percent carbon by mass is measured at two different locations. To compare the means of the two different locations, it must first be determined whether the standard deviations of the two locations are different. 2 T Location 1 | Location 2 (% C) (% C) 30.40 30.10 30.20 30.90 30.30 30.20 30.40 30.70 30.30 30.30 For each location, calculate the standard deviation and report it with two significant...

We were unable to transcribe this imageAs you can see from this equation, the value of t becomes larger as the difference between the means becomes larger, or the standard error of the difference in the means becomes smaller For example, consider two groups of data with the following parameters Group Mean 20 10 Sample variance 10 10 Sample size In this case 20-10 10 10 10 2+2 The last thing we need to calculate is known as the degrees...
Have you ever wondered what it means to click the “offset carbon emissions” button when you book a flight or train trip? It adds a small cost to your ticket, but how does this reduce emissions? The money is typically used to fund projects that reduce carbon emissions. One such project type is the introduction of more efficient cooking stoves into communities. Much of the world uses inefficient charcoal or wood stoves that result in excessive indoor air pollution, deforestation,...
Please do all questions... A cell phone battery manufacturer claims that one of their batteries for a particular cell phone will outperform a competitor's equivalent brand. To establish this claim, a researcher selected samples of the two brands of batteries and perform accelerated tests on them in the lab under identical conditions. A random sample of 55 of the manufacturer's battery was selected and placed on test. A corresponding random sample of 55 of the competitor's battery was also put...
1.The owner of a golf course wants to determine if his golf course is more difficult than the one his friend owns. He has 8 golfers play a round of 18 holes on his golf course and records their scores. Later that week, he has the same 8 golfers play a round of golf on his friend's course and records their scores again. The average difference in the scores (treated as the scores on his course - the scores on...
Suppose you work for a political pollster during an election year. You are tasked with determining the projected winner of the November election. That is, you wish to determine if the number of votes for Candidate 1 is less than the votes for Candidate 2. What are the hypotheses for this test? 1) HO: μ1 = μ2 HA: μ1 ≠ μ2 2) HO: μ1 > μ2 HA: μ1 ≤ μ2 3) HO: μ1 ≤ μ2 HA: μ1 > μ2 4)...

You are curious about the average number of yards Matthew Stafford throws for each game for the Detroit Lions. You randomly select 23 games and see that the average yards per game is 344.5 with a standard deviation of 27.8 yards. You want to create a 95% confidence interval for the true average number of yards per game he throws. What is the margin of error for this estimate? Question 1 options: 1) 1.5833 2) 5.7967 3) 12.0216 4) 9.9538...
