Question 194635
The mean height of a certain kind of plant is 171 centimeters. Suppose we want to carry out a hypothesis test to see if the mean height when these plants are treated with a certain chemical differs from 171. State the null hypothesis Ho and the alternative hypothesis H1 that we would use for this test. 
Ho: u = 171
H1: u is not equal to 171
