Question

A recent report published in USA Today indicated that a common family of four spends $ 490 a month on food. Suppose that the distribution of food expenses for a family of four follows a symmetric distribution, with an average dispersion of $ 90. Based on the information obtained, we want to identify: what percentage of families spends: more than $ 30 and less than $ 490 in food per month; less than less than $ 430 a month in food; between $ 430 and $ 600 per month in food; between $ 500 and $ 600 per month in food; and less than $ 410 or more than 570 per month in food. Perform the analysis required for the study detailing an individual interpretation sentence for each situation.

1. According to an article published on the Web site,
Facebook users spend an average of 190 minutes per month checking
and updating their Facebook pages. Suppose that the current
distribution of time spent per month checking and updating a
member’s Facebook page is normally distributed with a mean of 190
minutes and a standard deviation of 53.4 minutes. For a randomly
selected Facebook member, determine the probability that the amount
of time that he or she spends per month...
