A study examined the interactions in a children's museum. (Interactions by visitors to the museum included show-and-tell, learning, teaching, refocusing, participatory play, advocating, and disciplining interactions.) Researchers observed a sample of 143 meaningful interactions, of which 87 were led by children and the rest were led by adult caregivers. Form a 95% confidence interval around the proportion. What is the difference between the highest possible value and the lowest possible value? Round your final answer to three decimal places as needed.

Suppose a file (whose name is given through an argument by the user) contains student names and their scores (ranging from 0 to 100): i.e. each line contains a student name (just the first name with no space inside) and the student’s score separated by a space. Find out who has the highest score with what score, and who has the lowest score with what score. Also, calculate the average of all of the scores. Do not use arrays to solve this problem.

6. The Very Long Baseline Array radio interferometer (VLBA) has a longest baseline of 8000 km and can operate at frequencies as high as 44 GHz. The Keck interferometer has a baseline of 100 m and operates at a near-infrared wavelength of 2 micron. (a) Which instrument has the highest angular resolution (smallest diffraction angle)? (b) For the VLBA, what is the smallest distance two radio transmitters could be on the Moon that could still be discerned? Use a lunar distance of 384,000 km.
