I need help with C
The data in the table represent the wealth, in billions of dollars, of six people. Use the data to answer questions (a) through (c). (Assume that sampling is without replacement.) 29 24 28 29 20 25 samples of size 2. O B. 21 23 25 27 29 21 23 25 27 29 D. ... 21 23 25 27 29 21 23 25 27 29 c. For a random sample of size 2, determine the probability that the mean wealth of the two people obtained will be within 3 ($3 billion) of the population mean. The probability is 0.800 (Round to three decimal places as needed. Use the answers from part (a) and part (b) to find this answer.) Question is complete.
