A teacher administers a standardized math test to a sample group of 75 students. The mean test score (out of 300 possible points) is 235 points. From previous studies, it is known that the population standard deviation of the test scores is 28 points. Construct a 95% confidence interval for the population mean test score.

Apply the appropriate rounding rule if necessary. You can use the "Format Cells..." option in Excel to show the required number of decimal places (Excel will automatically round the number up or down).Do not showany symbols or words in your answer.

A 95% confidence interval for the population mean test score is from _______________ to __________
