James had a peach that was 98 mm in diameter. one day he watered it with a magical solution, and it grew to 188,869 mm in diameter approximately how many times as large did the diameter of the peach become after james watered it? and i would love it if you could me convert in to scientific notation

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
