We have drawn a smooth curve that represents a distribution,
a. Identify the shape of the distirbution with regard to modality.
b. Identify the shape of the distribution with regard to symmetry (or non symmetry)
c . If the distribution is unimodal and non symmetric, classify it as either right skewed or left skewed.

Q 2.14
The Fulbright Program. The U.S. government's flagship international educational exchange program, the Fulbright program, is sponsored by the Bureau of Educational and Cultural Affairs. Fulbrights are awarded based on "academic and leadership potential. providing the opportunity to exchange ideas and contribute to finding solutions to shared international concerns." For 2012-2013, the top 10 doctoral/research institutions receiving Fulbright awards are as shown in the following table. The success rate gives the number of grants per application, expressed as a percentage. Identify the type of data provided by the information in each column of the table.
Q.2.140
Children of U.S presidents. The information please alamanae provides the number of children of each of the U.S presidents. A frequency histogram of number of children by president, through president Bararck H. Obama , as it follows.
State whether the distribution is symmetric, right skewed, or left skewed.
Q.2.141
Clocking the Cheetah. The cheetah (Acinonyx jubatus) is the fastest land mammal and is highly specialized to run down prey. The cheetah often exceeds speeds of and, according to the online document "Cheetah Conservation in Southern Africa" (Trade \& Environment Database (TED) Case Studies, Vol. 8, No. 2) by J. Urbaniak, the cheetah is capable of speeds up to . Following is a frequency histogram for the speeds, in miles per hour, for a sample of cheetahs.
State whether the distribution is symmetric, right skewed, left skewed.
Q.2.142
Malnutrition and Poverty. R. Reifen et al. studied various nutritional measures of Ethiopian school children and published their findings in the paper "Ethiopian-Born and Native Israeli School Children Have Different Growth Patterns" (Nutrition, Vol. 19 , pp. ). The study, conducted in Azezo, North West Ethiopia, found that malnutrition is prevalent in primary and secondary school children because of economic poverty. A frequency histogram for the weights, in kilograms (kg), of randomly selected male Ethiopianborn school children ages years old is as follows.
State whether the distribution is symmetric, right skewed, or left skewed.
Q. 2.143
The Court's Burrow. The subterranean color (Spalacopus cyan) is a social rodent that lives in large colonies in underground burrows that can reach lengths of up to 600 meters. Zoologists S. Begall and M. Gallardo studied the characteristics of the burrow systems of the subterranean color in central Chile and published their findings in the Journal of Zoology, Landen (Vol. 251, pp. 53-60). A sample of 51 burrows, whose depths were measured in centimeters, yielded the following frequency histogram.
Q. 2.144
Baltimore Ravens. From Player Roster, the official roster of the 2013 Super Bowl champion Baltimore Ravens, we obtained the heights, in inches, of the players on that team. A dot plot of those heights is as follows.
