TiNspire for two sample t-tests (Hypothesis Testing)

This video shows how to get the p-value to compare with a 10% level of significance. 10% = 0.1 and if the p-value is smaller than 0.1, we reject our null hypothesis. Conclusion: We have enough evidence to REJECT the null hypothesis and there is a significant difference between newborns from the group of smoking mothers and non-smoking mothers.
