A local grocery store sells a variety of bagels fresh every morning. The mean weight of these bagels is 3 oz with a standard deviation of 0.7 oz. Suppose we take a random sample of 49 of sesame bagels and record their weights. The mean weight of our sample of 49 slices is 3.1oz. True or False: based on this sample, it seem likely that sesame bagels weigh more than the other bagels.

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.
