Data accumulated by the National Climatic Data Center shows that the average wind speed in miles per hour for St. Louis,Missouri
Marat540 [252]

Answer:

The  value is  \sigma  =  8.5    

Step-by-step explanation:

From the question we are told that

  The  population mean is  \mu  =  9.7

   The  proportion is  P(X >x) =  0.2245

   The value considered is  x =  11.6

Generally given that the speed measurement is normally distributed we have that

   P(X >  11.6) =  P(\frac{ X - \mu }{ \sigma } >  \frac{11.6 - 9.7}{ \sigma } )  = 0.2245

Generally

   \frac{X - \mu}{ \sigma }  = Z(The  \ z -score \ of \  X )

P(X >  11.6) =  P(Z>  \frac{11.6 - 9.7}{ \sigma } )  = 0.2245

Hence

     \frac{ 11.6 - 9.7}{ \sigma}  =  0.2245

  \sigma  =  8.5
