Question
A math teacher claims that she has developed a review course that increases the scores of students on the math portion of a college entrance exam. Based on data from the
administrator of the exam, scores are normally distributed with µ = 524. The teacher obtains a random sample of 2000 students, puts them through the review class, and finds that the
mean math score of the 2000 students is 532 with a standard deviation of 117. Complete parts (a) through (d) below.
ICCEI
(a) state the fun and emauve nypoteses.
Ho: μ = 524, H₁: H > 524
(b) Test the hypothesis at the a=0.10 level of significance. Is a mean math score of 532 statistically significantly higher than 524? Conduct a hypothesis test using the P-value
approach.
Find the test statistic.
to =
(Round to two decimal places as needed.)
