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 da from the administrator of the exam, scores are normally distributed with u = 514. The teacher obtains a random sample of 1800 students, puts them through the reu class, and finds that the mean math score of the 1800 students is 521 with a standard deviation of 113. Complete parts (a) through (d) below. OC. Ho p>514, H,: u#514 O D. Ho =514, H,: p#514 (b) Test the hypothesis at the = 0.10 level of significance. Is a mean math score of 521 statistically significantly higher than 514? Conduct a hypothesis test using the P-value approach. Find the test statistic. to = 2.63 (Round to two decimal places as needed.) Find the P-value. The P-value is (Round to three decimal places as needed.)

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 p = 514. The teacher obtains a random sample of 1800 students, puts them through the review
class, and finds that the mean math score of the 1800 students is 521 with a standard deviation of 113. Complete parts (a) through (d) below.
OC. Ho p>514, H, p#514
O D. Ho p=514, H p#514
(b) Test the hypothesis at the a= 0.10 level of significance. Is a mean math score of 521 statistically significantly higher than 514? Conduct a hypothesis test using
the P-value approach.
Find the test statistic.
to = 2.63
(Round to two decimal places as needed.)
Find the P-value.
The P-value is
(Round to three decimal places as needed.)
