Question

IV. Given the dotplot below, calculate the mean and standard deviation. Label ?, ?, and -? on the dot plot. Use these values to determine whether the distribution could be normal. Collection 1 Histogram 20. mean = 21. standard deviation = 22. ? - ? = 23. ? + ? = 24. What percent of the data is within one ? of ?? 25. Does the distribution appear Normal?

IV. Given the dotplot below, calculate the mean and standard deviation. Label μ, σ, and -σ on the dot plot. Use these values to determine whether the distribution could be normal. 20. mean = 21. standard deviation = 22. μ - σ = 23. μ + σ = 24. What percent of the data is within one σ of μ? 25. Does the distribution appear Normal?
