Suppose you have entered a data set into your graphing calculator and want to determine how many data values fall within the range from $35$ to $95$, inclusive. Which calculator function or process would you most likely use to find this count?

• A. Use the frequency table or histogram feature to count the number of values between $35$ and $95$.
• B. Use the mean function to find the average of all values between $35$ and $95$.
• C. Use the standard deviation function to determine the spread of values between $35$ and $95$.
• D. Use the regression function to model the relationship between $35$ and $95$.

Answer: (A)

Verified step by step guidance

1. Understand that the goal is to find the number of data values within a specific range, from 35 to 95 inclusive.
2. Recall that the mean function calculates the average of data values, which does not directly provide a count of values within a range.
3. Recognize that the standard deviation function measures the spread or variability of data, but it does not count how many values fall within a certain interval.
4. Know that the regression function is used to model relationships between variables, not to count data points within a range.
5. Identify that the frequency table or histogram feature groups data into intervals (bins) and shows how many data points fall into each bin, making it the appropriate tool to count values between 35 and 95.
