Horace, a golfer, claims that his drive distance is less than 225 meters, on average. Several of his friends do not believe him, so he decides to do a hypothesis test, at a 10 % significance level, to persuade them. He hits 23 drives. The mean distance of the sample drives is 210 meters. Horace knows from experience that the standard deviation for his drive distance is 14 meters. H 0 : 225 ; H a : < 225 = 0.1 (significance level) What is the test statistic ( z -score) of this one-mean hypothesis test, rounded to two decimal places? Provide your answer below
