Question 10Answer part C only!! 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= 520.The teacher obtains a random sample of 2200 students, puts them through the review class, and finds that the mean math score of the 2200 students is 526 with a standard deviation of 114. Complete parts (a) through (d) below......(a) State the null and alternative hypotheses.Ho:H - 520, H,: H520(b) Test the hypothesis at the a = 0.10 level of significance. Is a mean math score of 526 statistically significantly higher than 520? Conduct a hypothesis test using the P-value approach.Find the test statistic.to(Round to two decimal places as needed.)= 2.47Find the P-value.The P-value is 0.007.(Round to three decimal places as needed.)Is the sample mean statistically significantly higher?A. Yes, because the P-value is less than a = 0.10.B. No, because the P-value is greater than a = 0.10.C. No, because the P-value is less than a = 0.10.D. Yes, because the P-value is greater than a = 0.10.(c) Do you think that a mean math score of 526 versus 520 will affect the decision of a school admissions administrator? In other words, does the increase in the score have any practical significance?O A. Yes, because the score became more than 1.15% greater.B. No, because every increase in score is practically significant.O C. No, because the score became only 1.15% greater.O D. Yes, because every increase in score is practically significant.
