Question

Can someone please help me to explain it, please, and answer it. Answer only parts A and B. All the images come together. The accompanying data are the percentage of babies born prematurely in a particular year for the 50 U.S. states and the District of Columbia (DC). (a) The smallest value in the data set is \( 8.1 \)

Answer 1

The smallest value of premature births in this dataset is 8.1%. The estimated average percentage of a disease rate is calculated by averaging the given range, resulting in an estimated average of 43%, with the United States being below this average at a rate of 33.9%.

Step-by-step explanation:

To answer the question related to the proportion of premature babies, we use the given data points. For part (a), the smallest value of premature births is given as 8.1%. This is likely the minimum rate of premature births for the set of states being considered.

For part (b), we are provided with another data set where the disease rates range from 11.4% to 74.6%. To estimate the best average percentage affected by the disease across these countries, we can calculate the mean by adding the lowest value and the highest value, then dividing by 2.

This gives us (11.4 + 74.6) / 2 = 43% as an estimate for the average disease rate. Considering the United States has an average disease rate of 33.9%, it is below this computed average.
