Final answer:
The correct interpretation is option c which indicates that there is a significant difference in mvpa between nonobese and obese groups, with a t-statistic of 5.97 and a p-value of less than .001. option c is correct.
Step-by-step explanation:
The correct interpretation of the statistical result provided is option c: "mvpa of nonobese group is significantly different from that of obese group, t(957.37) = 5.97, p < .001." This conclusion is based on the understanding that a low p-value (in this case, less than .001) suggests that the null hypothesis (which typically posits that there is no effect or no difference) should be rejected.
The t-statistic indicates the calculated difference between groups, and the degrees of freedom (957.37 in this dataset) give context to the t-value in terms of the sample size and variance. The p-value is significantly less than the typical alpha level of 0.05 which indicates that the probability of observing such an extreme value of the test statistic under the null hypothesis is very low.
Therefore, there is sufficient statistical evidence to conclude that the mean values of mvpa are significantly different between the nonobese and obese groups.
