The First Certificate Test (FCE) was taken by 1,546,101 students from three countries: China, Japan, and India. Scores range from 20 to 200. The means and standard deviations for each country are shown in the table below. Assuming that the results of Chinese students follow a normal distribution, describe its normal distribution.

	Mean	StDev
China	118	59
Japan	106	57
India	149	61

a) The graph of the normal density curve N( 118, 59) is a bell-shaped curve which is centered at the mean 118 and has a horizontal scale such that 95% of the area under the curve falls within one standard deviation of the mean.

b) The graph of the normal density curve N( 118, 59) is a bell-shaped curve which is centered at the mean 118 and has a horizontal scale such that 95% of the area under the curve falls within three standard deviations of the mean.

c) The graph of the normal density curve N( 59, 118) is a bell-shaped curve which is centered at the mean 59 and has a horizontal scale such that 95% of the area under the curve falls within two standard deviations of the mean.

d) The graph of the normal density curve N( 118, 59) is a bell-shaped curve which is centered at the mean 118 and has a horizontal scale such that 95% of the area under the curve falls within two standard deviations of the mean.
