A paired-sample t-test was conducted to assess the impact of a boot camp on juvenile self-esteem. With a p-value below 0.05, we reject the null hypothesis, indicating a significant change in self-esteem ratings before and after the boot camp.
To determine if the boot camp affects self-esteem ratings for juveniles, you can perform a paired-sample t-test. The null hypothesis
is that there is no significant difference, and the alternative hypothesis
is that there is a significant difference. Let's conduct the t-test using the given data:
Before (in a list): 17, 19, 12, 14, 17, 13, 15, 20
After (in a list): 19, 15, 15, 17, 22, 21, 15, 23
The t-test will output a p-value. If the p-value is less than 0.05, you can reject the null hypothesis, suggesting that there is a significant difference in self-esteem ratings before and after the boot camp.
It's important to note that this analysis assumes the data is normally distributed and the variances are equal. If these assumptions are violated, alternative methods may be more appropriate.
