a) Calculate the mean, median, sample variance, and standard deviation of these results.
b) Calculate the 95% confidence intervals for this data set. Explain what these results are telling us in your own words. (Analyze - one sample t-test 95%)
c) What does a standard deviation tell you?
d) Suppose it is believed that the average weight for these children is 3 kg. At the 5% level of significance test whether the true weight for this group is 3 kg against the alternative hypothesis that the average weight is greater than 3 kg. You may assume that the data are normally distributed.
e) Draw a P-P plot for this data set. Would you consider this data to be normally distributed? Please justify your answer. (descriptive P-P plot)
