1. Write the null and alternative hypotheses for these tests: part a) has been started to show you the format for the answer:

a) One-group, single-sided t-test for a mean = Ho: mu <=  _____    Ha: mu > _____ where the ___ represents the value we’re interested in. Could also be >= vs <

b) One-group, two-sided t-test for a mean

c) Two-group, single-sided t-test for two means

d) Two-group, two-sided t-test for two means Ho: mu1-mu2= 0 Ha: mu1-mu2<>0

e) Paired t-test for mean of differences

f) Analysis of variance for g different group means

g) Simple linear regression

h) Chi-squared
