Part (d) Calculate the sample mean. (Round your answer to one decimal place.) \( \bar{x} \approx \) Enter your answer

To calculate the sample mean, you'll want to sum all the data points in your sample and then divide that total by the number of data points. For example, if you have data points like 5, 7, 9, and 11, you would add them up (5 + 7 + 9 + 11 = 32) and then divide by the number of points (4 in this case), which gives you a mean of 8. Make sure to round your answer to one decimal place for clarity! Remember that rounding can sometimes lead to common mistakes, especially when it involves keeping track of decimal points. After adding your data points and dividing by the count, double-check your final result before rounding. Always ensure that each step is clear to avoid confusion—it's worth the extra moment!
