Are children with higher exposure to pesticides more likely to develop ADHD (attention-deficit/hyperactivity disorder)? In a stu

dy, authors measured levels of urinary dialkyl phosphate (DAP, a common pesticide) concentrations and ascertained ADHD diagnostic status (Yes/No) for 1139 children who were representative of the general US population.1 The subjects were divided into two groups based on high or low pesticide concentrations, and we compare the proportion with ADHD in each group.

Write a equation that is parallel to 5x-y=4
ozzi
Let's have this equation equal y first. All we have to do is add y to both sides and subtract 4 from both sides.
5x-4=y
Now, to get a parallel line, the y intercept has to change. The y intercept (the -4 in the equation) can be an infinite amount of number but -4.
Let's choose 6. We would have 5x+6=y or you could put it in the way the other equation was, 5x-y=-6.

Suppose you take a simple random sample of size n=175 from the population of Reese's Pieces, still assuming that 45% of this pop
Gnesinka [82]

Answer:

The  probability is  P(0.35

Step-by-step explanation:

From the question we are told that

  The sample size is  n =  175

   The population proportion is  p =  0.45

   

Generally the mean of the sampling distribution is  \mu_{x} =  0.45

 Generally the standard deviation is mathematically represented as  

        \sigma_{x} =  \sqrt{\frac{p (1-p)}{n} }

=>      \sigma_{x} =  \sqrt{\frac{0.45 (1-0.45)}{175} }

=>      \sigma_{x} = 0.0376

Generally the probability of  that the sample proportion of orange candies will be between 0.35 and  0.55 is  

      P(0.35 <  X < 0.55) =  P( \frac{0.35 - 0.45}{0.0376} <  \frac{X -\mu_{x}}{\sigma_{x}}  <  \frac{0.55 - 0.45}{0.0376} )

=>   P(0.35

Generally \frac{X - \mu_{x}}{\sigma_{x}}  =  Z  (The \  standardized \  value \  of  X)

So

    P(0.35

=>  P(0.35

From the z-table  

    P(  Z< 2.6595 ) = 0.99609

and

    P(  Z< - 2.6595 ) = 0.0039128

So

   P(0.35

=> P(0.35
