Answer 1

Independent samples t-Test was performed using MS Excel. The test has been performed using equal variance. Following is the output:

Answer a)

From the result above, it can seen that the p-value (the significance) is 0.0035

Answer b)

Since p-value = 0.0035 < 0.05 significance level, we reject null hypothesis.

Thus, the difference between the mean age first diagnosed for males and females is statistically significant.
