Step 3c: What is the 95% Confidence Interval (95% CI)?

Step 4: You need to write a conclusion paragraph about your statistical conclusions on the question "do males and females differ in their reaction times?" 

(4 key points - dot points allowed)

Now we’ve got the necessary statistics to calculate the p-value and 95% CI

Step 3b: Calculate the T-statistic.

Step 3b: Based on your p-value in the previous question please answer if the following statement is TRUE or FALSE?

As the p-value is > 0.05, the p-value is not significant. We do not reject the null hypothesis. There is no difference in reaction time between males and females.

Step 3b: What is the p-value?

Step 3a: Calculate Standard Error (SE):

Hint calculate SD_p² 

Step 3a: Calculate the degrees of freedom:

Step 3a: Calculate the difference in means (Female – Male)

Step 3a: What is the T-multiplier? (2 decimal places)

Step 1: State the Null & Alternative hypotheses
