A national standardized test consists of three parts: critical reading, mathematics, and writing. Suppose each part of the test isscored on a 200- to 800-point scale with a median of approximately 510. Scores for each part of the test can be assumed to besymmetric. Use the following data to test the hypothesis that the population median score for the students taking the writing portionof the test is 510.635 701 439 447502447405 453 471 476590 337 387Ho: Median > 510H: Median < 510aState the null and alternative hypotheses.Ho: Median # 510H: Median = 510Ho: Median < 510H₂: Median = 510Ho: Median = 510H₂: Median # 510464Ho: Median ≤ 510Ha:: Median > 510Find the value of the test statistic.T+ = 39514Find the p-value.

Researchers wondered whether the size of a person's brain was related to the individual's mental capacity. They selected a sample of 3 females and 3 males and measured their MRI counts and IQ scores. The data is reported on the right. Females Males MRI IQ MRI 10 866,664 132 965,355 132 790,620 135 1,001,121 141 856,473 141 1,079,550 135 O Treat the MRI count as the explanatory variable. Compute the linear correlation coefficient between MRI count and IQ for both the males and the females. Do you believe that MRI count and IQ are linearly related? The linear correlation coefficient for females is. The linear correlation coefficient for males is. (Round to three decimal places as needed.) Are MRI count and IQ linearly related? linear The linear correlation coefficient for females is close to ▼so relation exists between MRI count and IQ for females. The linear correlation coefficient for linear relation exists between MRI count and IQ males is close to for males. SO

3. Can SAT scores predict college performance? Let x be a variable that represents SAT score of a computer science major, and let y be a variable that represents a student’s GPA upon graduation. A random sample of n =15 computer science majors provided their SAT scores and GPAs: x 1232 1070 1086 1287 1130 1048 1121 1095 1135 1208 1333 1160 1186 1243 1261 y 3.52 2.91 2.4 3.47 3.47 2.37 2.4 2.24 3.02 3.32 3.59 2.54 3.19 3.71 3.58 The scatter diagram for the SAT score and GPA is given below: (a) Find the sample correlation coefficient r.
