A report from the office of the superintendent claims that the

average reading test score of 4th grade students in the school

district is 76. A group of parents suspects that the real mean is

lower than this reported score so they draw a random sample

consisting of 37 4th grade student reading scores. they find that

the sample mean is 74 and the sample standard deviation is 4.5. To

test the superintendent’s office claim, state the correct null and

alternative hypotheses: a) H0 : LaTeX: /muÎ¼Î¼ LaTeX: /geâ‰¥â‰¥ 76 VS Ha
