Can u guys help me with this question please?? 25 random samples of 30 people each were measured for their daily water usage. The mean for each sample is included in the dot plot. Use the values to estimate the mean water usage for the population. What is the margin of error for this estimate based on these values? (Round to the nearest tenth of a gallon.)

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
