Question
Refer to the data set below and determine whether the requirement of a normal distribution is satisfied.
Refer to the data set below (body mass index of men) and determine whether the requirement of a normal distribution is satisfied. Assume that this requirement is loose in the sense that the population distribution need not be exactly normal, but it must be a distribution that is basically symmetric with only one mode. Is the requirement of a normal distribution satisfied? No. The points in the normal quantile plot do not lie close to a straight line. Yes. The points in the normal quantile plot lie reasonably close to a straight line. No. The histogram of the data is not boll shaped. There is also more than one outlier. Yes. The points in the normal quantile plot exhibit some systematic pattern that is not a straight-line pattern.Explanation / Answer
Answer: B. Yes Than points in the normal quantile plot lie reasonably close to a straight line.
Explanation: We get the normal probability plot where all the points scatter close to the straight line with the mean value of 25.9 along with the standard deviation of 3.440. Here the p-value for normality test is greater than .05 (or .01). We fail to reject the null hypothesis at 5% (or 1%) level of significance and there is sufficient evidence to conclude that the requirement of a normal distribution is satisfied here.
