Step 1
x̄ = (18 + 12 + 15 + 20 + 31 + 17 + 22 + 20 + 22 + 21 + 14 + 16) / 12 x̄ = 20.25 Show more…

Use a normal probability plot to assess whether the sample data could have come from a population that is normally distributed. A random sample of 25 years between 1890 and 2005 was obtained, and the amount of snowfall, in inches, for Memphis was recorded. (Source: National Oceanic and Atmospheric Administration). $$\begin{array}{ccccc}24.0 & 7.9 & 1.5 & 0.0 & 0.3 \\\hline 0.4 & 8.1 & 4.3 & 0.0 & 0.5 \\\hline 3.6 & 2.9 & 0.4 & 2.6 & 0.1 \\\hline 16.6 & 1.4 & 23.8 & 25.1 & 1.6 \\\hline 12.2 & 14.8 & 0.4 & 3.7 & 4.2\end{array}$$
