A researcher used a sample of n =16 adults between the ages of 40 and 45. For each person, the researcher recorded the difference between the ratings obtained while smiling and the rating obtained while frowning. On average the cartoons were rated as funnier when the participants were smiling, with an average difference of MD = 1.6, with SS = 135. Are the cartoons rated as significantly funnier when the participants are smiling ? Use a one-tailed test with α = .05. The null hypothesis in words is: The cartoons were rated as significantly funnier when the participants were smiling than when the participants were frowning. The alternative hypothesis in symbols is: H1: µD> 0 Critical T value :1.753 T-statistics: 2.13 P-value: 0.0249 r2=.2327 QUESTION: & if APA is correct Your decision is Group of answer choices A.Reject the null hypothesis because the t-statistic is greater than the critical t-value B.Reject the null hypothesis because the t-statistic is not greater than the critical t-value C.Fail to reject the null hypothesis because the t-statistic is greater than the critical t-value D.Fail to reject the null hypothesis because the t-statistic is not greater than the critical t-value APA: Cartoons were rated funnier smiling: There are significant differences for cartoons being rated funnier when participants were smiling rather than when frowning in adults between the ages of 40 & 45.

QUESTION: & if APA is correct
Cartoons were rated funnier smiling: There are significant differences for cartoons being rated funnier when participants were smiling rather than when frowning in adults between the ages of 40 & 45. (MD=1.6, SD=2.5), t(15)=2.13, p<.05, d=.5 using one-tailed test.
Given information,
A researcher used a sample of n =16 adults between the ages of 40 and 45. For each person, the researcher recorded the difference between the ratings obtained while smiling and the rating obtained while frowning. On average the cartoons were rated as funnier when the participants were smiling, with an average difference of MD = 1.6, with SS = 135.
Claim:
Are the cartoons rated as significantly funnier when the participants are smiling.
Null hypothesis:
There is no significant difference for carton being rated funnier when participants were smiling rather than when frowning.
H0:µD=0
Alternative hypothesis:
