Answer:
The mean is  [tex]\mu_{x} = 0.145[/tex]
The standard deviation is  [tex]\sigma  =  0.0111 [/tex]   Â
Step-by-step explanation:
From the question we are told that
  The population proportion is  p  =  0.145 Â
  The sample size is  n  =  1000
 Â
Generally because the sample size is sufficiently large  the mean of this sampling distribution  is  [tex]\mu_{x} = p = 0.145[/tex]
Generally the standard deviation is mathematically represented as Â
  [tex]\sigma  =  \sqrt{ \frac{p(1- p )}{n } } [/tex]
=> [tex]\sigma  =  \sqrt{ \frac{ 0.145 (1- 0.145  )}{  1000  } } [/tex]
=> [tex]\sigma  =  0.0111 [/tex]     Â
