Question

Write a function in Python to perform a two sample t-test. The t-test should be unpaired and you may assume that the samples have equal variance. The function should have:

specify a choice of alternative hypotheses by giving arguments “two-sided”, “less”, or “greater”. If no such alternative is given, then the default should be “two-sided”
specify a parameter mu indicating the true difference in means under the null hypothesis. If unspecified, the default should be mu=0.
result should be a dict with the labeled values of the t-statistic and the p-value
function should be my_ttest(x,y,mu,alternative), where x and y are the two samples being compared.
use the function scipy.stats.t.cdf to calculate p-values
generate random samples for testing using npr.normal
