**Understanding SAT Critical Reading Scores Using Normal Distribution**In this exercise, we will use the normal distribution to analyze SAT critical reading scores. The mean SAT critical reading score is 502, with a standard deviation of 109. Assuming the variable $ x $ is normally distributed, we can explore the following questions:**(a)** What percent of the SAT verbal scores are less than 550?**(b)** If 1000 SAT verbal scores are randomly selected, how many would you expect to be greater than 525?To assist with these calculations, you can refer to the standard normal table:- [Click to view page 1 of the standard normal table.](#)- [Click to view page 2 of the standard normal table.](#)**Calculation Steps:**1. **(a)** Approximately __% of the SAT verbal scores are less than 550. (Round to two decimal places as needed.)2. **(b)** You would expect that approximately __ SAT verbal scores would be greater than 525. (Round to the nearest whole number as needed.)This analysis helps in understanding the distribution and likelihood of certain scores occurring within the SAT verbal scores dataset.**Graph/Diagram Explanation:***Note: Since no specific graph or diagram is provided in the image, no further elaboration is included on graphical content.*Please ensure to calculate the exact percentages and numbers using the standard normal distribution table to fill in the blanks for a comprehensive understanding.**Interactive Elements:**- Time Remaining: 00:56:36- Next Button to proceed with the exercise.For more accurate and interactive analysis, utilize the provided links to the standard normal table pages.--- This educational resource provides a structured approach to learning about normal distribution, particularly in the context of SAT scores.
