1. Write up your results in APA format. Your write-up should include sample mean(s)/standard deviation(s), t-statistics, degrees of freedom, p-value, and a conclusion. (use the examples from lecture). [3 points]

Answer 1

Result A one sample t-test, with α 0.05 as criterion of significance, was conducted. It revealed that for the observed sample (N-80), average of the variable What is your gender?" is significantly higher than the hypothesized value 0 (M0.363, SD 0.484), (79) 6.702, p< 0.001. Furthermore it can be stated with 95% confidence that the true difference between the sample mean and the hypothesized means is CI [0.25, 0.47]. Hence it can be concluded that there is enough evidence to reject the null hypothesis in favour of the altemate, that is, the evidence suggests that the variable "What is your gender?" is unlikely to have a population mean equal to zero.
