Which of these statements is TRUE?
Group of answer choices
C is not significantly different than D.
A is not significantly different than D.
B is not significantly different than C.
A is not significantly different than C
Group of answer choices
C is not significantly different than D True, because the p-value between C and D is 0.6128 > alpha = 0.05. So, fail to rejedt H0, implies that no significant difference between C and D
A is not significantly different than D False, because the p-value between A and D is <0.0001 which is less than alpha that implies there is a significant difference between A and D.
B is not significantly different than C.False because the p-value is 0.0006 < alpha implies a significant difference
A is not significantly different than C, False because the p-value is 0.006 < alpha implies a significant difference

Lab 12-Stat 212 Online Suppose we have the following scenario: Rapid drainage of floodwater is crucial to prevent damage during heavy rains. Several designs for a drainage canal were considered for a certain city. Each design was tested four times, to determine how long it took to drain the water in a reservoir. The following table presents the drainage times, in minutes. Mean S. Dev. Variance (i.e. SD") n The overall average is x = 39.67 Type 1 44 4.12...
An experimenter wants to know if having a pet or friend present while taking a stressful math test helps reduce anxiety. She recruits 120 people to participate in the study and each person takes a difficult math test under a strict time limit. The participants are also randomly assigned to take the test alone, with a friend in the room, or with a therapy dog in the room. After taking the test, participants completed a survey that assessed how stressful...

Data Analysis is designed to build a strong foundation for development of statistical literacy and statistical thinking. Both are essential for business success and further studies in business. Recent research showed that “On average for 15-year-old Australian students, females achieved at a significantly lower level than male students (in mathematics)” (p.2, Buckley 2016) 1 . However, there is also research evidence that “Despite the stereotype that boys do better in math and science, girls have made higher grades than boys...
