Which of the following is the correct way to report the results of a dependent sample t test?
Group of answer choices
The t test was significantly different between group one and group two
On average, the sample glucose level after the new diet (M=132.7, SE = 0.43) was significantly lower than that before the new diet (M= 155.7, SE = 0.46), t (35) = 8.38, p = .001.
t = 9.42, p = .001
The high school GPA statistically predicted college mathematics performance, R squared = .12, F (1,148) = 20.18, p < .001
From the given information above,
Following is the correct way to report ,

The price to earnings ratio (P/E) is an important tool in financial work. A random sample of 14 large U.S. banks (J. P. Morgan, Bank of America, and others) gave the following P/E ratios.† 24 16 22 14 12 13 17 22 15 19 23 13 11 18 The sample mean is x ≈ 17.1. Generally speaking, a low P/E ratio indicates a "value" or bargain stock. Suppose a recent copy of a magazine indicated that the P/E ratio of...
The first two questions refer to the following information: Researchers developed an online tool to help ESL students learn prepositions and metaphors. A study measuring academic success in ESL students randomly sampled 100 Spanish speaking ESL students using traditional ESL classes and the new language tool and 81 Portuguese speaking ESL students using traditional ESL classes and the new language tool, and scored them on a common English fluency scale (higher score representing greater degree of fluency). The researchers suspected...
The authors of a paper titled "Age and Violent Content Labels
Make Video Games Forbidden Fruits for Youth" carried out an
experiment to determine if restrictive labels on video games

how much they wanted to play the game. The description also
included an age rating. Some participants read the description with
an age restrictive label of 7+,...

Item 1 In the case below, the original source material is given along with a sample of student work. Determine the type of plagiarism by clicking the appropriate radio button. Original Source Material Student Version Analysis of patterns in time (APT) is a method for gathering information about observable phenomena such that probabilities of temporal patterns of events can be estimated empirically. If appropriate sampling strategies are employed, temporal patterns can be predicted from APT results. Finally, APT is compared...
