I added aquestionas images Q1.: What are the quartiles for the following set of numbers? Q2 What are the quartiles for the following set of numbers? Q3. What is the interquartile range for the following set of numbers?

he student scores in an examination are 35, 30, 25, 26, 40, 44, 36, 54, 64, 65, 75, 60, 70, 85, 90, 92, 46, 52, 63, 52. The daily pocket money (in Rs.) for the same students (respectively) are 110, 110, 120, 140, 150, 140, 150, 210, 200, 140, 210, 240, 300, 260, 500, 270, 310, 550, 450, 500. Find the following:-  (a) Regression of scores on pocket money (b) Regression of pocket money on scores (c) Derive Pearson’s Correlation coefficient from the above two regression coefficients  

Assume the SAT Mathematics Level 2 test scores are normally distributed with a mean of 400 and a standard deviation of 100. Show all work. Just the answer, without supporting work, will receive no credit. (a) Consider all random samples of 64 test scores. What is the standard deviation of the sample means? (Round your answer to three decimal places) (b) What is the probability that 64 randomly selected test scores will have a mean test score that is greater than 425? (Round your answer to four decimal places)

I am trying to run a regression in excel. But I am getting this message “Regression – Estimated output table will extend beyond the bounds of the worksheet. Please choose a different reference.” I tried to use a new workbook instead and I am still getting the same message. My sample size is 125,000+ Any advice will help.
