Measurements of wind speed on a certain island were taken over a period of one year. A box-and-
whisker plot of the data is obtained where the LQ= 39 and UP=63. It is suggested that wind speed can be modelled approximately by a normal distribution with mean μ and standard deviation σ.
(i) Estimate the value of μ.
(ii) Estimate the value of σ.
The value of μ=(63+39)/2=51, but can someone help me how to find the σ?1 AnswerMathematics4 years ago
