Which of the following is true about standard deviation? The first step in calculating the standard deviation is calculating the square root. The second step in calculating the standard deviation is to subtract each measurement from the intermediate value and then square that difference. The last step in calculating the standard deviation is to sum the squared values and divide by the number of values minus one. Standard deviation is a type of average where the positive and negative numbers sum to zero. The amount of difference of the measurements from the central value is called the sample standard deviation.

ADVERSE SELECTIONSomet Health Insurance Company wants to sell a health insurance product for $700 permonth. There is no requirement for healthy people to have insurance coverage. Thecompany conducts a survey to see how different populations respond to the proposed cost.People with no illnesses and disabilities, generally the young and healthy, respond that theydo not spend $700 on healthcare in an entire year, and most feel they would not waste somuch money on premiums when the chance of needing surgery or expensive healthcaretreatments is so small. However, older, sicker people think that $700 per month is a greatdeal, as most of them spend far in excess of this amount on healthcare. It seems like agreat deal for them. What will happen to the costs of the health insurance if only the older, sicker peopleenroll?
