案例：

tt)
print 't-statistic = %6.3f pvalue = %6.4f' % (tt,pval)
t-statistic =  0.391 pvalue = 0.6955

可执行代码

means = [0.0539,4,8,3,6,9,1]

stds = [5,7,9]

n = 20

output = []

for sm,std,m in zip(means,stds,mu):

print("value:",sm,std)
tt = (sm-m)/(std/np.sqrt(float(n)))      # t-statistic for mean
pval = stats.t.sf(np.abs(tt),n-1)*2  # two-sided pvalue = Prob(abs(t)>tt)
# print('t-statistic = %6.3f pvalue = %6.4f' % (tt,pval))
output.append(format(pval))
print("t".join(output))
