The proportion of adults aged 15-49 who are living with HIV/AIDS is 0.5% in Latin America, 1.0% in the Caribbean, 0.9% in Eastern Europe and Central Asia and 0.6% in North America. Suppose we include the proportion for Sub-Saharan Africa (5.0%) to this data set and calculate the standard deviation. Would you expect it to be significantly larger, smaller or remain about the same as the standard deviation of the proportions without the observation from Sub-Saharan Africa? remain about the same significantly smaller significantly larger unable to determine from the information given
