An insurance company crashed four cars in succession at 5 miles per hour. The cost of repair for each of the four crashes was ​$421​, ​$469​, ​$416​, ​$232   . Compute the​ range, sample​ variance, and sample standard deviation cost of repair.

The average chef at a restaurant earns $17 an hour with a deviation of $1.75. What are the chances that someone is earning more than $20 an hour?

A  semiconductor  manufacturer  produces devices  used  as  central  processing  units  in personal  computers. The speed of the devices (in  megahertz)  is  important  because  it determines  the  price  that  the  manufacturer can  charge  for  the  devices.  The  following table  contains  measurements on 120  devices. a.  Calculate  the  sample  mean,  sample variance,  and  standard  deviation. b.  Find  the  median  and  quartiles  for  the  data. c.  Construct  a  box  plot  of  the  data.  Find  the  interquartile  range  and  determine  the  number  of  outliers

Consider the following data: 10,6,1,2,8,9 Calculate the value of the sample standard deviation. Round your answer to one decimal place.
