The next six questions refer to the following scenario: A random sample of 25 students were asked to self-identify as "statistics-lovers" or "statistics-adorers." 16 students self-identified as "lovers" and 9 students as "adorers." Below table summarizes the mean of a statistics test and standard deviation that was given after the self-identification. Test the following hypothesis at alpha=5% (0.05). HO: Mean Statistics Lovers = Mean Statistics Adorers HA: Mean Statistics Lovers Mean Statistics Adorers You can assume equal variance.

The next 10 questions refer to the following scenario: According the World Health Organization, the Body Mass Index (BMI=Weight in Kilograms/Height in Meters?) of a healthy 5-year old girl is 15. After Palmyra, Syria, got liberated from the Islamic State, the World Food Program asks you to conduct an early assessment situation of the nutritional situation in Palmyra. You measure the height and weight of a random sample of 225 five-year old girls and obtain a sample BMI average of = 14.5785 and a sample standard deviation 0. 01 the hypothesis that the children of Palmyra are of s=2.25. Test at a undernourished as measured by the BMI.
