Q1 t-test independent

[toncho11]

Hi,

Thank you for your wonderful tutorial on hypothesis testing with Python.

I have a suggestion to use the latest version of stats.ttest_ind and set the alternative hypothesis to 'greater' instead of dividing the p-value. Dividing the p-value of a two sided t-test might not be so accurate as using a one-sided t-test. Below is the updated code.

ttest,p_value = stats.ttest_ind(sync, asyncr , alternative = 'greater')
print("p value:%.8f" % p_value)

if p_value < 0.05:
    print("Reject null hypothesis")
else:
    print("Fail to reject null hypothesis")
