Draw a normal distribution. Shade in the two tails. Mark the value of the mean, the tcritical
values, and your t value. Below that, make a decision regarding the null hypothesis and
whether your data were statistically significant. Explain what your decision means in
terms of whether spraying people with water influences smoking. Justify your answer –
talk about whether your t value was in the critical region and what that tells you about the
likelihood of obtaining your data if the null hypothesis were true.
