Gnesinka [82]

Answer: 32

Step-by-step explanation:

The expression that is equivalent to 2^2 divided by 2/2^4 would be calculated as:

= 2^2 ÷ 2/2^4

= 4 ÷ 2/16

g In 2013, the Pew Research Foundation reported that 43% of U.S. adults report that they live with one or more chronic condition
SOVA2 [1]

Answer:

We are 95% confident that the true proportion of U.S. adults who live with one or more chronic conditions is between 39.7% and 46.33%

Step-by-step explanation:

From the question we are told that

  The  sample  proportion is \r p = 43\%  = 0.43

   The  standard error is SE =  0.017

Given that the confidence level is 95%  then the level of significance is mathematically represented as  

      \alpha =  (100-95)\%

=>   \alpha = 0.05

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.96

Generally the margin of error is mathematically represented as

     E = Z_{\frac{\alpha }{2} } *  SE

=>    E = 1.96 *  0.017

=>     E = 0.03332

Generally 95% confidence interval is mathematically represented as

      \r p -E <  p <  \r p +E

=>   0.43 -0.03332 <  p <  0.43 + 0.03332

=>    0.39668 <  p <  0.46332

Converting to percentage

(0.39668 * 100)<  p <  (0.46332*100)        

39.7\% <  p < 46.33 \%
