The illustration depicts a normal distribution curve for the prices paid for a specific model of HD television. Key statistical metrics include a mean price of $2000 and a standard deviation of $115.**Diagram Description:**The curve is a typical bell-shaped normal distribution centered at $2000. The x-axis marks prices ranging from $1655 to $2345 at intervals of $115, reflecting the standard deviation. **Questions:**1. **What is the approximate percentage of buyers who paid less than $1655?** - Answer: $ \_\_\_\_ \%$2. **What is the approximate percentage of buyers who paid less than $1770?** - Answer: $ \_\_\_\_ \%$3. **What is the approximate percentage of buyers who paid between $2000 and $2230?** - Answer: $ \_\_\_\_ \%$4. **What is the approximate percentage of buyers who paid between $2000 and $2115?** - Answer: $ \_\_\_\_ \%$5. **What is the approximate percentage of buyers who paid between $1885 and $2115?** - Answer: $ \_\_\_\_ \%$6. **What is the approximate percentage of buyers who paid between $2000 and $2345?** - Answer: $ \_\_\_\_ \%$Note: This exercise is designed to encourage the application of normal distribution concepts, such as understanding areas under the curve relative to the mean and standard deviation.

ats 2. In the mid-19th century, Sir Francis Galton demonstrated, through extensive data collection, that many human characteristics such as height and IQ are distributed throughout the entire population in accordance with the normal distribution. Galton recorded the heights of 8585 men in Great Britain. This forms a normal distribution with a mean of 67 inches and standard deviation of 2.5 inches. (a) Graph this normal distribution and label the x-axis. (b) What proportion of these men were between 66 and 68 inches tall? belool vin (c) What fraction of the adult male population in Great Britain was within one standard deviation of the mean height? [Use the normal distribution function in Excel, not the Empirical Rule] (d) What height corresponds to the 95th percentile in the Galton study?
