5 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 Class Height 150 150 Height 160 160 Height 170 170 Height 180 Height 2 180 Multiple Choice O Observed 10 6 18 17 9 Suppose the value of the test statistic is 7 71 Using the critical value approach decision and conclusion are Expected pi 0 09 0 21 0 31 0 25 0 14 do not reject the null hypothesis conclude that heights are not normally distributed reject the null hypothesis conclude that heights are normally distributed reject the null hypothesis conclude that heights are not normally distributed do not reject the null hypothesis conclude that heights are normally distributed
