Calculating p-values
In order to determine whether to choose the null hypothesis or the alternative hypothesis, you need to calculate a p-value from the z-score.
You'll now return to the late shipments dataset and the proportion of late shipments.
The null hypothesis, \(H_{0}\), is that the proportion of late shipments is six percent.
The alternative hypothesis, \(H_{A}\), is that the proportion of late shipments is greater than six percent.
The observed sample statistic, late_prop_samp
, the hypothesized value, late_prop_hyp
(6%), and the bootstrap standard error, std_error
are available. norm
from scipy.stats
has also been loaded without an alias.
