Romashka-Z-Leto [24]

Answer:

a

\= x  =  82

b

s =  9.64

Step-by-step explanation:

From the question we are told that

    The data is  87  91  86  82  72  91   60  77  80  79  83  96

Generally the point estimate for the mean is mathematically represented as

    \= x  =  \frac{\sum  x_i }{n}

=>  \= x  =  \frac{87 +91 + 86 + \cdots  + 96}{12}

=>    \= x  =  82

Generally the point estimate for the standard deviation  is mathematically represented as

      s =  \sqrt{\frac{ \sum ( x_i  - \= x )^2 }{ n -1 } }

=>     s =  \sqrt{\frac{ ( 87 - 82  )^2 +( 91 - 82  )^2 + \cdots + ( 96 - 82  )^2  }{ 12 -1 } }

=>     s =  9.64
