Practice/Exercises: Solve the following problems. 1. In a given normal distribution, the sample mean is 75 and sample standard deviation is 4. Find the corresponding z-score of a student who receive a score of 70. 2. In a given normal distribution, the population mean is 80 and population standard deviation is 2.5. Find the corresponding z-score of a student who receive a score of 85. 3. On a final examination in Mathematics, the mean was 76 and the standard deviation was 5. Determine the standard score of a student who received a score of 88 assuming the scores are normally distributed. 4. Lodi gets a score of 85 in a Biology test and 80 in a Math test. Scores in the Biology test have a mean of 75 and a standard deviation of 5. Scores in the Math test have a mean of 70 and standard deviation of 4. In which subject is her standing better assuming that the scores in the two subjects are normally distributed?
