The heights (in cm) for a random sample of 60 males were measured. The sample mean is 166.55, the standard deviation is 12.57, the sample kurtosis is 0.12, and the sample skewness is −0.23. The following table shows the heights subdivided into non-overlapping intervals. Using the p-value approach and α = 0.05, the decision and conclusion are ________.
A) reject the null hypothesis; conclude that heights are normally distributed
B) reject the null hypothesis; conclude that heights are not normally distributed
C) do not reject the null hypothesis; conclude that heights are normally distributed
D) do not reject the null hypothesis; conclude that heights are not normally distributed
